Computer Running Slow? 20 Ways to Speed Up Windows 11/10 Instantly (2026)

Q: Why is my computer suddenly running slow after being fast?

Sudden slowdowns usually have specific triggers rather than gradual degradation. The most common causes are: a Windows update that caused conflicts or is still configuring in the background (check Windows Update settings to see if updates are pending or stuck), malware infection from a recent download or website visit (run a full scan immediately with Windows Security and Malwarebytes), a recent software installation that autostarts and consumes resources (check Task Manager startup programs), hard drive beginning to fail (run CrystalDiskInfo to check health), or overheating due to dust accumulation blocking vents (check temperatures with HWMonitor). If the slowdown started today, think about what you installed, downloaded, or changed yesterday, and reverse it.

Q: How can I tell if I need more RAM or if something else is wrong?

Open Task Manager (Ctrl + Shift + Esc) and click the Performance tab, then Memory. Watch the memory usage while you use your computer normally. If memory consistently runs at 80100% usage, you definitely need more RAM. Look for memory "spikes" when opening programs if usage jumps to 90%+ and stays there, that's a RAM bottleneck. Also check the "Committed" memory amount if it's close to or exceeds your physical RAM, Windows is using your hard drive as memory (called "paging"), which causes severe slowdowns. However, if your RAM usage is only at 4060% but your computer is still slow, the problem is elsewhere likely CPU, hard drive, or malware. Modern Windows needs minimum 8GB RAM; 16GB is ideal for multitasking.

Q: Will a factory reset delete all my files and programs?

Windows Reset offers two options: "Keep my files" and "Remove everything." If you choose "Keep my files," Windows will preserve documents, photos, videos, and personal files in your user folders (Desktop, Documents, Downloads, Pictures, Music, Videos), but it WILL remove all installed programs, apps, and system settings you'll need to reinstall programs like Microsoft Office, Adobe, browsers, games, etc. Importantly, programs don't include data files, so your Word documents and Excel spreadsheets are safe. If you choose "Remove everything," Windows performs a complete wipe, deleting everything like a brand new computer. Always backup important files to an external drive or cloud storage before resetting, regardless of which option you choose. Make a list of programs you need to reinstall and save browser bookmarks.

Q: Is it safe to disable Windows Search and other services?

Disabling Windows Search is safe and won't harm your computer it only affects the speed of file searches. Instead of instant results, searches will take a few seconds longer as Windows scans files in realtime rather than using the prebuilt index. This tradeoff is worthwhile on older computers where the indexing process constantly consumes CPU resources and slows everything else down. However, be very careful about disabling other services. Only disable services you understand critical Windows services (anything with "Windows," "System," "Network," or "Security" in the name) should generally be left alone. The safe approach is to use msconfig to disable startup programs and thirdparty services (after checking "Hide all Microsoft services") rather than touching core Windows services in services.msc.

Q: My laptop is always hot and the fan is loud is this slowing it down?

Yes, absolutely. When laptops overheat, they automatically throttle (slow down) the CPU to prevent hardware damage, which makes everything sluggish. Constant high temperatures indicate poor airflow from dust buildup in vents and fans, or driedout thermal paste that no longer transfers heat effectively. First, turn off your laptop and use compressed air to blow dust out of the vents you'll likely see clouds of dust come out. Second, ensure you're using the laptop on hard, flat surfaces, not soft beds or couches that block ventilation. Third, consider a laptop cooling pad ($1530) which adds extra fans underneath. If still overheating, the thermal paste between CPU and heatsink may need replacement this requires disassembly and is best done by professionals unless you're comfortable opening your laptop. Normal temperatures are 3050°C idle and 6080°C under load; anything consistently over 85°C indicates overheating problems.

Q: Can cleaning up my hard drive really make my computer faster?

Yes, but not for the reason most people think. Deleting files doesn't speed up your processor or add RAM. However, when your hard drive is over 85% full, Windows performance degrades significantly for several technical reasons: Windows needs free space for virtual memory (paging file) to supplement RAM, temporary files created during operations, system restore points, and Windows updates that need to download and extract files before installing. When space is critically low, Windows constantly juggles these temporary files, causing slowdowns. Additionally, hard drives (HDDs, not SSDs) slow down as they fill up because data becomes more fragmented and the drive head has to move more to find free space. Keep at least 1520% of your drive free (minimum 2030GB on a typical system drive) for optimal performance. Use Storage Sense to automatically clean up temporary files.

Q: What's the difference between restarting and shutting down my computer?

This is important: Windows 10 and 11 use "Fast Startup" which means shutting down doesn't actually close everything it hibernates the Windows kernel to speed up the next boot. This means issues with memory leaks, hung processes, and system state accumulate over time even if you shut down nightly. Restart, however, does a complete shutdown of all processes and a fresh boot, clearing all temporary issues. That's why IT support always says "have you tried restarting?" it's legitimately different from shutdown. To get a true shutdown instead of Fast Startup hibernate, either use Restart, or disable Fast Startup: Settings → System → Power & battery → Additional power settings → Choose what the power buttons do → Change settings that are currently unavailable → Uncheck "Turn on fast startup." For best performance, restart your computer at least weekly.

Q: Are "PC optimizer" and "driver updater" software worth it or scams?

Most are scams or at best unnecessary bloatware, though a few legitimate ones exist. The free versions typically scan your computer and claim to find "hundreds of issues" but then require payment to fix them these "issues" are usually harmless or exaggerated. Many install adware, collect your data, or slow down your computer themselves. Windows has builtin optimization tools that work well: Disk Cleanup, Storage Sense, Windows Update (which includes driver updates), and the builtin troubleshooters. For driver updates, always go directly to manufacturer websites (NVIDIA, AMD, Intel for graphics; Dell, HP, Lenovo for laptops) rather than trusting thirdparty software. The few legitimate tools worth considering are CCleaner (use carefully, basic version is free), Malwarebytes (excellent for malware), and manufacturerspecific utilities like Dell SupportAssist or Lenovo Vantage. Never pay for "registry cleaners" or "PC speedup" software advertised through popups or aggressive ads.

Q: How long should my computer take to start up?

Boot times vary based on hardware, but here are 2026 benchmarks for Windows 11/10 from pressing power button to usable desktop: With SSD and modern hardware (2018+): 1025 seconds is normal, under 15 is excellent. With SSD and older hardware (20122018): 2040 seconds is acceptable. With traditional hard drive (HDD): 4090 seconds is typical, over 2 minutes indicates problems. If your boot time significantly exceeds these ranges, the main culprits are too many startup programs (check Task Manager → Startup), pending Windows updates configuring at startup, or a failing hard drive. Upgrading from HDD to SSD is the single biggest boot time improvement you can make often reducing 90second boots to 15 seconds. Also ensure Fast Startup is enabled (Settings → Power options) unless you experience driver issues. After disabling unnecessary startup programs, you should see 3060 second improvement immediately.

Q: When should I upgrade my computer vs. fix it?

Use this costbenefit analysis: If your computer is under 4 years old with decent specs (Intel i5/Ryzen 5 or better, 8GB+ RAM), almost always worth fixing upgrading to SSD ($50100) and/or adding RAM ($4070) can make it feel brand new for under $150 total. If your computer is 57 years old, evaluate: can it run Windows 11? Does it have upgrade paths for RAM and storage? If yes, moderate repairs/upgrades are worthwhile; if no, start planning replacement. If your computer is 8+ years old, repairs rarely make financial sense unless you're doing them yourself as a learning experience a $300 refurbished business computer will outperform it. The exception is if you have emotional attachment or the computer has specialized hardware/software that's expensive to replace. Also consider: if multiple components are failing simultaneously (hard drive dying AND bad RAM AND old processor), replacement is smarter than trying to fix everything. A good rule: if total repair/upgrade costs exceed 4050% of a new computer that would meet your needs, buy new instead.

Your computer used to be fast. Now it takes forever to start up, programs freeze constantly, and even simple tasks feel like pulling teeth.

Sound familiar? You're not alone. Over 5 million people search "computer running slow" every single month, making it one of the most common tech frustrations worldwide.

The good news? You don't need to buy a new computer or hire expensive tech support. In most cases, you can speed up your slow Windows 11 or Windows 10 computer in just minutes using the proven methods in this guide.

This comprehensive guide covers 20 free solutions that work for laptops and desktops, from quick 2-minute fixes to advanced optimization techniques. Let's get your computer running like new again.

Why Is My Computer So Slow? (Top 10 Causes)

Understanding why your computer slowed down helps you fix it faster:

Most Common Culprits:

Too Many Startup Programs - 30+ apps launching when you boot up
Insufficient RAM - Running out of memory with multiple programs open
Hard Drive Nearly Full - Less than 15% free space remaining
Malware and Viruses - Hidden programs consuming resources
Outdated Drivers - Especially graphics, chipset, and storage drivers
Background Apps Running - Dozens of programs you're not using
Hard Drive Issues - Fragmentation (HDD) or degradation
Windows Updates Pending - System waiting to install or configure updates
Browser Overload - Too many tabs, extensions, and cached data
Overheating - Dust buildup causing CPU throttling

The average computer has 15-20 fixable issues slowing it down. Let's tackle them systematically.

⚡ QUICK FIXES (Under 5 Minutes)

Start here for immediate results. These fixes work 80% of the time and require no technical knowledge.

Fix #1: Restart Your Computer (Seriously!)

When did you last restart? If it's been more than a week, this alone might solve your problem.

Why This Works:

Clears RAM (memory) buildup
Closes hidden background processes
Installs pending Windows updates
Resets temporary system glitches
Fixes memory leaks from programs

How to Do It:

Save all your work
Click Start Menu → Power → Restart (NOT shut down)
Wait for complete restart
Don't open anything for 2 minutes (let Windows settle)

Pro Tip: Restart weekly for optimal performance. Many people use "sleep" for months, which accumulates memory problems.

Fix #2: Close Unnecessary Programs and Browser Tabs

Each open program and browser tab uses RAM. When you run out of RAM, Windows slows to a crawl using your hard drive instead (which is 100x slower).

Check What's Running:

Press Ctrl + Shift + Esc (opens Task Manager)
Click Processes tab
Click Memory column to sort by usage
Look for programs using 500MB+ that you're not using

What to Close:

Google Chrome with 20+ tabs (each tab uses 100-300MB)
Spotify, iTunes when not listening to music
Microsoft Teams, Slack, Discord when not chatting
Adobe Creative Cloud, Steam when not using
Old Office documents you finished hours ago

Quick Close Method:

Right-click the taskbar → Task Manager
Select memory-hungry program
Click End Task

You should see speed improvement immediately after closing 3-5 resource-heavy programs.

Fix #3: Disable Startup Programs (HUGE Impact)

This is the #1 reason computers start up slowly. Every program that launches at startup adds 10-30 seconds to boot time and consumes RAM even when you're not using them.

Windows 11:

Press Ctrl + Shift + Esc → Task Manager
Click Startup apps tab
Look at Status and Startup impact columns
Disable programs you don't need at startup:
Right-click program
Select Disable

Windows 10:

Open Task Manager
Click Startup tab
Right-click unnecessary programs → Disable

What to Disable (Safe to Turn Off):

✅ iTunes Helper, Spotify, Zoom, Adobe Creative Cloud
✅ Microsoft OneDrive (if you don't use cloud storage)
✅ Steam, Discord, Epic Games Launcher
✅ HP/Dell/Lenovo utility software (bloatware)
✅ Cloud backup services you don't actively use
✅ Printer software, scanner utilities

What to KEEP Enabled:

❌ Antivirus software (Windows Security, Norton, McAfee)
❌ Graphics drivers (Intel, NVIDIA, AMD)
❌ Audio drivers (Realtek, etc.)
❌ Windows Security Notification

Expected Result: Boot time reduced by 30-60 seconds, RAM usage drops by 500MB-2GB.

Fix #4: Delete Temporary Files and Cache

Windows accumulates GIGABYTES of junk files - temporary downloads, update cache, browser data, and system logs you'll never need.

Using Disk Cleanup (Built-in Tool):

Press Windows + R
Type cleanmgr and press Enter
Select your C: drive → OK
Click Clean up system files (requires admin)

Check these boxes:

Temporary files
Downloads folder (if empty or unwanted)
Recycle Bin
Temporary Internet Files
Windows Update Cleanup
Delivery Optimization Files

Click OK → Delete Files

**This typically frees 2-10GB of space and speeds up file operations.
**

Windows 11 Storage Sense (Better Option):

Press Windows + I (Settings)
Go to System → Storage
Click Temporary files
Check all boxes except "Downloads"
Click Remove files

Clear Browser Cache:

Chrome:

Press Ctrl + Shift + Delete
Select All time
Check "Cached images and files"
Click Clear data

Edge:

Press Ctrl + Shift + Delete
Select All time
Check cached data
Click Clear now

Browsers accumulate 500MB-5GB of cache that slows page loading.

Fix #5: Run Full Virus and Malware Scan

Malware can secretly consume 50-90% of your CPU without you knowing, making your computer unbearably slow.

Windows Security (Built-in, Free):

Press Windows + I → Settings
Click Privacy & Security → Windows Security
Click Virus & threat protection
Click Scan options
Select Full scan (not Quick scan)
Click Scan now
Wait 30-60 minutes for completion

Additional Scan with Malwarebytes (Recommended):

Download Malwarebytes (free version) from malwarebytes.com
Install and run
Click Scan
Remove all detected threats
Restart computer

Malwarebytes catches threats Windows Security often misses - browser hijackers, adware, and PUPs (potentially unwanted programs).

Signs of Malware:

Random pop-ups and ads
Browser redirects to strange websites
New toolbars you didn't install
Computer fan running constantly
CPU usage at 100% when idle
Programs opening by themselves

After removing malware, many users report 50-80% speed improvement.

Fix #6: Check for Windows Updates

Outdated Windows versions run slower and have security vulnerabilities. Updates include performance improvements and bug fixes.

How to Update:

Press Windows + I → Settings
Click Windows Update
Click Check for updates
Install all available updates
Restart when prompted

Important: Some updates require multiple restarts. Keep checking until it says "You're up to date."

If Updates Keep Failing:

Run Windows Update Troubleshooter:

Settings → System → Troubleshoot → Other troubleshooters
Find "Windows Update" → Click Run

Clear Update Cache:

Press Windows + R
Type services.msc
Find "Windows Update" → Right-click → Stop
Open File Explorer → Go to C:\Windows\SoftwareDistribution
Delete everything in this folder
Restart computer
Try updating again

Fix #7: Adjust Visual Effects for Performance

Windows 11/10 use fancy animations and effects that consume resources. Disabling them makes your computer feel significantly faster, especially on older hardware.

Optimize for Performance:

Press Windows + R
Type sysdm.cpl and press Enter
Click Advanced tab
Under "Performance," click Settings
Select Adjust for best performance

This disables all effects

OR select Custom and keep only:

Show thumbnails instead of icons
Smooth edges of screen fonts
Show window contents while dragging

Click Apply → OK

Expected Result: Windows feels 20-30% snappier, especially when opening folders and programs.

Fix #8: Disable Background Apps

Dozens of apps run in the background even when you're not using them, consuming RAM and CPU.

Windows 11:

Settings → Apps → Startup
Disable unnecessary apps
Then go to Privacy & security → Background apps
Turn off apps you don't need running constantly

Windows 10:

Settings → Privacy → Background apps

Toggle off apps you don't need:

Weather
News
Maps (unless you use it)
Microsoft Store (can update manually)
Tips (you don't need this)
Mail (if you use web-based email)

Keep enabled: Antivirus, OneDrive (if you use it), messaging apps you actively use

🔧 INTERMEDIATE FIXES (10-15 Minutes)
These require a bit more technical knowledge but deliver major performance gains.

Fix #9: Upgrade to SSD (Biggest Speed Boost)

If you're still using a traditional hard drive (HDD), upgrading to an SSD is the single biggest performance improvement you can make - often 5-10x faster.

How to Tell If You Have HDD or SSD:

Press Windows + R
Type dfrgui and press Enter
Look at "Media type" column
Hard disk drive = HDD (slow)
Solid state drive = SSD (fast)

Why SSD Matters:

Boot time: HDD = 60-120 seconds | SSD = 10-20 seconds
Program launch: HDD = 5-15 seconds | SSD = 1-2 seconds
File operations: 10x faster copying, moving, opening files
Overall responsiveness: Everything feels instant

Cost & Installation:

500GB SSD: $40-60
1TB SSD: $60-100
Installation: DIY (easy for desktops, moderate for laptops) or professional ($50-100)

ROI: An SSD upgrade breathes new life into 5-10 year old computers for under $100.

Fix #10: Add More RAM (If You Have Less Than 8GB)

RAM is your computer's working memory. Not enough RAM = constant slowdowns and freezing.

Check Current RAM:

Press Windows + Pause/Break
Look at "Installed RAM"
Or: Task Manager → Performance tab → Memory

How Much RAM You Need (2026):

4GB or less: Barely usable, constant slowdowns
8GB: Minimum for smooth Windows 11/10
16GB: Ideal for multitasking, gaming, creative work
32GB+: Professional work, video editing, heavy multitasking

Signs You Need More RAM:

Task Manager shows 80-100% memory usage
Computer freezes when opening multiple programs
Browser tabs crash frequently
"Not enough memory" error messages

Upgrade Cost:

8GB DDR4: $25-40
16GB DDR4: $40-70
Installation: Easy for desktops, moderate for laptops (some have soldered RAM)

Before buying: Check if your laptop/motherboard supports RAM upgrades.

Fix #11: Defragment Hard Drive (HDD Only)

If you have an HDD (not SSD), fragmentation slows file access as data gets scattered across the drive.

⚠️ IMPORTANT: Only defrag HDDs, NEVER defrag SSDs (it wears them out without benefit)

How to Defragment:

Press Windows + R
Type dfrgui and press Enter
Select your C: drive
Click Optimize (previously called "Defragment")
Wait for completion (can take 30min-2 hours)

Schedule Automatic Defragmentation:

In the same window, click Change settings
Set to weekly for HDDs

For SSDs - Enable TRIM:

SSDs don't need defragmentation but need TRIM:

Open Command Prompt as Administrator
Type: fsutil behavior query DisableDeleteNotify
If it says "DisableDeleteNotify = 0" → TRIM is enabled (good)
If it says "= 1" → Enable with: fsutil behavior set DisableDeleteNotify 0

Fix #12: Update All Drivers

Outdated drivers cause crashes, freezes, and poor performance.

** Critical drivers to update:**

Priority Driver Updates:

Graphics drivers (GPU) - NVIDIA, AMD, Intel
Chipset drivers - Motherboard controller
Storage controller drivers - SSD/HDD performance
Network adapter - Wi-Fi and Ethernet

Method 1: Device Manager

Press Windows + X → Device Manager
Expand each category
Right-click device → Update driver
Select Search automatically

Method 2: Manufacturer Websites (Better)

Graphics Drivers:

NVIDIA: nvidia.com/Download/index.aspx

Intel: intel.com/content/www/us/en/download-center/home.html

Laptop Drivers:

Dell: dell.com/support
HP: support.hp.com
Lenovo: support.lenovo.com
ASUS: asus.com/support

Method 3: Driver Update Software

Free options:

Windows Update (Settings → Windows Update → Advanced options → Optional updates)
Manufacturer utilities (Dell SupportAssist, HP Support Assistant, Lenovo Vantage)

Paid options (use with caution):

Driver Booster, Driver Easy - can work but may install unnecessary software

Fix #13: Disable Windows Search Indexing (On Older PCs)

Windows Search indexes all your files for faster searches, but this process can slow down older computers significantly.

Check If Indexing Is Causing Slowdown:

Open Task Manager
Look for SearchIndexer.exe or Microsoft Windows Search Indexer
If using 30%+ CPU constantly → disable it

Disable Search Indexing:

Press Windows + R
Type services.msc
Find Windows Search
Right-click → Properties
Set "Startup type" to Disabled
Click Stop → Apply → OK
Restart computer

Trade-off: File searches will be slower, but overall computer performance improves on older hardware.

Fix #14: Adjust Power Settings to High Performance

Windows defaults to "Balanced" power plan, which throttles CPU to save energy. High Performance mode keeps CPU at full speed.

Windows 11:

Press Windows + I → Settings
Click System → Power & battery
Set "Power mode" to Best performance

Windows 10:

Press Windows + R
Type powercfg.cpl
Select High performance power plan

If not visible, click "Show additional plans"

Advanced Power Settings (Max Performance):

In Power Options, click Change plan settings → Change advanced power settings

Adjust these settings:

Processor power management → Minimum: 100%, Maximum: 100%
PCI Express → Link State Power Management: Off
Hard disk → Turn off hard disk after: Never
Wireless adapter → Power saving mode: Maximum Performance

Note: Laptops will drain battery faster. Use "Balanced" when on battery, "High Performance" when plugged in.

Fix #15: Clean Up Disk Space (Free Up Storage)

When your hard drive is over 85% full, Windows slows down dramatically because it needs free space for temporary files and virtual memory.

Check Storage:

Settings → System → Storage
See what's using space

What to Delete:

Large Files:

Old downloads (Downloads folder)
Installation files (.exe, .msi files)
Old videos and movies
Duplicate photos

Use Storage Sense:

Settings → Storage → Storage Sense
Turn it on
Click Configure Storage Sense
Set to clean temporary files automatically

Third-Party Tool - WinDirStat:

Download from windirstat.net
Shows visual map of what's using space
Makes it easy to find large files to delete

Move Files to External Drive:

Videos, photos, old projects
Anything you don't need daily access to
Keep at least 20-30GB free on C: drive

🚀 ADVANCED FIXES (15-30 Minutes)

For maximum performance, these techniques require more technical knowledge but deliver excellent results.

Fix #16: Clean Registry (Use With Caution)

The Windows Registry is a database of system settings. Over time, it accumulates invalid entries that can slow down your computer.

⚠️ WARNING: Backup registry before editing!

Using CCleaner (Safe & Easy):

Download CCleaner from ccleaner.com
Install (decline any bloatware during installation)
Go to Registry tab
Click Scan for Issues

Turn off all options:

"Let apps show me personalized ads"
"Show me suggested content in Settings app"
Windows welcome experience
Device usage suggestions

Disable Cortana (If Not Using):

Task Manager → Startup tab
Find Cortana → Disable

Fix #18: Perform Clean Boot (Identify Conflicting Software)

Third-party software conflicts cause slowdowns. Clean Boot starts Windows with minimal programs to identify culprits.

Steps:

Press Windows + R
Type msconfig → OK
Go to Services tab
Check Hide all Microsoft services
Click Disable all
Go to Startup tab
Click Open Task Manager
Disable all startup items
Close Task Manager
Click OK in System Configuration

Testing:

If computer is fast in Clean Boot → third-party software is the problem
Re-enable services/programs one by one to find the culprit
Uninstall problematic software

To Return to Normal:

Run msconfig again
Select Normal startup
Restart

Fix #19: Reset Windows (Last Resort - Full Refresh)

If nothing else works, resetting Windows reinstalls the operating system while optionally keeping your personal files.

Before Resetting:

Backup ALL important files to external drive or cloud
Write down installed programs you need to reinstall
Save browser bookmarks
Note WiFi passwords

How to Reset Windows:

Settings → System → Recovery
Under "Reset this PC," click Reset PC

Frequently asked questions

Why is my computer suddenly running slow after being fast?+

Sudden slowdowns usually have specific triggers rather than gradual degradation. The most common causes are: a Windows update that caused conflicts or is still configuring in the background (check Windows Update settings to see if updates are pending or stuck), malware infection from a recent download or website visit (run a full scan immediately with Windows Security and Malwarebytes), a recent software installation that auto-starts and consumes resources (check Task Manager startup programs), hard drive beginning to fail (run CrystalDiskInfo to check health), or overheating due to dust accumulation blocking vents (check temperatures with HWMonitor). If the slowdown started today, think about what you installed, downloaded, or changed yesterday, and reverse it.

How can I tell if I need more RAM or if something else is wrong?+

Open Task Manager (Ctrl + Shift + Esc) and click the Performance tab, then Memory. Watch the memory usage while you use your computer normally. If memory consistently runs at 80-100% usage, you definitely need more RAM. Look for memory "spikes" when opening programs - if usage jumps to 90%+ and stays there, that's a RAM bottleneck. Also check the "Committed" memory amount - if it's close to or exceeds your physical RAM, Windows is using your hard drive as memory (called "paging"), which causes severe slowdowns. However, if your RAM usage is only at 40-60% but your computer is still slow, the problem is elsewhere - likely CPU, hard drive, or malware. Modern Windows needs minimum 8GB RAM; 16GB is ideal for multitasking.

Will a factory reset delete all my files and programs?+

Windows Reset offers two options: "Keep my files" and "Remove everything." If you choose "Keep my files," Windows will preserve documents, photos, videos, and personal files in your user folders (Desktop, Documents, Downloads, Pictures, Music, Videos), but it WILL remove all installed programs, apps, and system settings - you'll need to reinstall programs like Microsoft Office, Adobe, browsers, games, etc. Importantly, programs don't include data files, so your Word documents and Excel spreadsheets are safe. If you choose "Remove everything," Windows performs a complete wipe, deleting everything like a brand new computer. Always backup important files to an external drive or cloud storage before resetting, regardless of which option you choose. Make a list of programs you need to reinstall and save browser bookmarks.

Is it safe to disable Windows Search and other services?+

Disabling Windows Search is safe and won't harm your computer - it only affects the speed of file searches. Instead of instant results, searches will take a few seconds longer as Windows scans files in real-time rather than using the pre-built index. This trade-off is worthwhile on older computers where the indexing process constantly consumes CPU resources and slows everything else down. However, be very careful about disabling other services. Only disable services you understand - critical Windows services (anything with "Windows," "System," "Network," or "Security" in the name) should generally be left alone. The safe approach is to use msconfig to disable startup programs and third-party services (after checking "Hide all Microsoft services") rather than touching core Windows services in services.msc.

My laptop is always hot and the fan is loud - is this slowing it down?+

Yes, absolutely. When laptops overheat, they automatically throttle (slow down) the CPU to prevent hardware damage, which makes everything sluggish. Constant high temperatures indicate poor airflow from dust buildup in vents and fans, or dried-out thermal paste that no longer transfers heat effectively. First, turn off your laptop and use compressed air to blow dust out of the vents - you'll likely see clouds of dust come out. Second, ensure you're using the laptop on hard, flat surfaces, not soft beds or couches that block ventilation. Third, consider a laptop cooling pad ($15-30) which adds extra fans underneath. If still overheating, the thermal paste between CPU and heatsink may need replacement - this requires disassembly and is best done by professionals unless you're comfortable opening your laptop. Normal temperatures are 30-50°C idle and 60-80°C under load; anything consistently over 85°C indicates overheating problems.

Can cleaning up my hard drive really make my computer faster?+

Yes, but not for the reason most people think. Deleting files doesn't speed up your processor or add RAM. However, when your hard drive is over 85% full, Windows performance degrades significantly for several technical reasons: Windows needs free space for virtual memory (paging file) to supplement RAM, temporary files created during operations, system restore points, and Windows updates that need to download and extract files before installing. When space is critically low, Windows constantly juggles these temporary files, causing slowdowns. Additionally, hard drives (HDDs, not SSDs) slow down as they fill up because data becomes more fragmented and the drive head has to move more to find free space. Keep at least 15-20% of your drive free (minimum 20-30GB on a typical system drive) for optimal performance. Use Storage Sense to automatically clean up temporary files.

What's the difference between restarting and shutting down my computer?+

This is important: Windows 10 and 11 use "Fast Startup" which means shutting down doesn't actually close everything - it hibernates the Windows kernel to speed up the next boot. This means issues with memory leaks, hung processes, and system state accumulate over time even if you shut down nightly. Restart, however, does a complete shutdown of all processes and a fresh boot, clearing all temporary issues. That's why IT support always says "have you tried restarting?" - it's legitimately different from shutdown. To get a true shutdown instead of Fast Startup hibernate, either use Restart, or disable Fast Startup: Settings → System → Power & battery → Additional power settings → Choose what the power buttons do → Change settings that are currently unavailable → Uncheck "Turn on fast startup." For best performance, restart your computer at least weekly.

Are "PC optimizer" and "driver updater" software worth it or scams?+

Most are scams or at best unnecessary bloatware, though a few legitimate ones exist. The free versions typically scan your computer and claim to find "hundreds of issues" but then require payment to fix them - these "issues" are usually harmless or exaggerated. Many install adware, collect your data, or slow down your computer themselves. Windows has built-in optimization tools that work well: Disk Cleanup, Storage Sense, Windows Update (which includes driver updates), and the built-in troubleshooters. For driver updates, always go directly to manufacturer websites (NVIDIA, AMD, Intel for graphics; Dell, HP, Lenovo for laptops) rather than trusting third-party software. The few legitimate tools worth considering are CCleaner (use carefully, basic version is free), Malwarebytes (excellent for malware), and manufacturer-specific utilities like Dell SupportAssist or Lenovo Vantage. Never pay for "registry cleaners" or "PC speedup" software advertised through pop-ups or aggressive ads.

How long should my computer take to start up?+

Boot times vary based on hardware, but here are 2026 benchmarks for Windows 11/10 from pressing power button to usable desktop: With SSD and modern hardware (2018+): 10-25 seconds is normal, under 15 is excellent. With SSD and older hardware (2012-2018): 20-40 seconds is acceptable. With traditional hard drive (HDD): 40-90 seconds is typical, over 2 minutes indicates problems. If your boot time significantly exceeds these ranges, the main culprits are too many startup programs (check Task Manager → Startup), pending Windows updates configuring at startup, or a failing hard drive. Upgrading from HDD to SSD is the single biggest boot time improvement you can make - often reducing 90-second boots to 15 seconds. Also ensure Fast Startup is enabled (Settings → Power options) unless you experience driver issues. After disabling unnecessary startup programs, you should see 30-60 second improvement immediately.

When should I upgrade my computer vs. fix it?+

Use this cost-benefit analysis: If your computer is under 4 years old with decent specs (Intel i5/Ryzen 5 or better, 8GB+ RAM), almost always worth fixing - upgrading to SSD ($50-100) and/or adding RAM ($40-70) can make it feel brand new for under $150 total. If your computer is 5-7 years old, evaluate: can it run Windows 11? Does it have upgrade paths for RAM and storage? If yes, moderate repairs/upgrades are worthwhile; if no, start planning replacement. If your computer is 8+ years old, repairs rarely make financial sense unless you're doing them yourself as a learning experience - a $300 refurbished business computer will outperform it. The exception is if you have emotional attachment or the computer has specialized hardware/software that's expensive to replace. Also consider: if multiple components are failing simultaneously (hard drive dying AND bad RAM AND old processor), replacement is smarter than trying to fix everything. A good rule: if total repair/upgrade costs exceed 40-50% of a new computer that would meet your needs, buy new instead.
