1. Restart Your PC Properly
Why a Simple Restart Often Works
Many performance issues are temporary and can be fixed by restarting your PC. This clears memory, closes background processes, and finalizes pending updates.
Steps for a Clean Reboot
-
Save all work and close open programs.
-
Click Start > Power > Restart.
-
Wait for Windows to finish the boot process before opening programs again.
Using Safe Mode for Troubleshooting
Safe Mode loads only essential Windows files. Restart your PC and press F8 (or Shift + Restart) to access Safe Mode if problems persist.
2. Check for Pending Updates
How to Access Windows Update Settings
-
Go to Start > Settings > Update & Security > Windows Update.
-
Click Check for updates to see pending updates.
Why Installing All Updates Can Fix Issues
Some slowdowns are caused by incomplete or buggy updates. Installing all pending updates ensures your system has the latest patches and bug fixes.
Restarting After Updates
Always restart your PC after updates. Some updates only take effect after a reboot, and this can restore performance.
3. Roll Back Problematic Updates
Identifying the Update Causing the Slowdown
Check Update History in Windows Update settings to see recent updates. Note any update installed right before the slowdown began.
How to Uninstall a Windows Update
-
Go to Settings > Update & Security > Windows Update > View update history > Uninstall updates.
-
Select the update causing issues and click Uninstall.
Precautions Before Rolling Back
-
Backup important files
-
Make a restore point in System Properties > System Protection
-
Avoid uninstalling critical security updates unless necessary
4. Update Device Drivers
How Outdated Drivers Affect Performance
Drivers control your hardware. Outdated or incompatible drivers can cause slowdowns, crashes, or system instability.
Updating Drivers via Device Manager
-
Press Windows + X > Device Manager.
-
Right-click a device and select Update driver.
-
Choose Search automatically for updated driver software.
Using Manufacturer’s Software for Updates
Many PC and GPU manufacturers provide software to update drivers automatically, like Intel Driver & Support Assistant or NVIDIA GeForce Experience.
5. Run Disk Cleanup and Optimize Storage
Deleting Temporary Files
Temporary files accumulate over time. Go to Settings > System > Storage > Temporary files to remove them.
Using Disk Cleanup Tool
-
Search Disk Cleanup in the Start menu.
-
Select the drive to clean and choose files to delete.
Defragmenting or Optimizing Drives
Optimize drives by going to This PC > Right-click drive > Properties > Tools > Optimize. SSDs are automatically optimized, while HDDs benefit from defragmentation.
6. Check for Malware or Unwanted Programs
Scanning with Windows Defender
-
Go to Settings > Update & Security > Windows Security > Virus & Threat Protection.
-
Click Quick Scan or Full Scan to detect threats.
Using Trusted Third-Party Antivirus
Third-party antivirus tools like Bitdefender, Kaspersky, or Malwarebytes provide extra protection and may detect threats Windows Defender misses.
Removing Startup Programs That Slow Down PC
-
Press Ctrl + Shift + Esc to open Task Manager.
-
Go to the Startup tab and disable unnecessary programs that launch on boot.
7. Adjust Visual Effects and Performance Settings
How Windows Visual Effects Affect Speed
Animations, transparency, and shadows look nice but consume resources, especially on older PCs.
Setting PC for Best Performance
-
Go to Start > System > Advanced system settings > Performance Settings.
-
Select Adjust for best performance to disable all effects.
Disabling Animations and Transparency
-
Settings > Accessibility > Visual effects
-
Turn off Transparency effects and Animation effects to speed up UI response.
8. Reset Windows (If All Else Fails)
When a System Reset Is Necessary
If your PC remains slow after all fixes, resetting Windows can restore performance to factory-like conditions.
How to Reset Without Losing Files
-
Go to Settings > Update & Security > Recovery > Reset this PC.
-
Choose Keep my files to retain personal data while reinstalling Windows.
Backing Up Important Data First
Even when keeping files, back up essential documents, photos, and projects to an external drive or cloud storage.
