Fortunately, there are several methods to fix corrupted files in Windows 10/11, ultimately improving your PC’s speed and performance. This troubleshooting guide assumes you are familiar with computer operations.
Basic
1. Clean Up Temporary Files for a Performance Boost
Temporary files, prefetch data, and recent file lists can accumulate over time, taking up space and potentially slowing things down. Here’s how to clean them up and potentially give your PC a performance boost:
- Disk Cleanup
- Open the Start menu and search for “Disk Cleanup.”
- Select your main drive (usually C:) and click “OK.”
- Wait for the scan to complete.
- Look for options like “Temporary Internet files,” “Downloaded Program Files,” and “Temporary files.” Check the boxes next to the ones you want to remove.
- Click “Clean up system files” for a more thorough cleaning (requires administrator permission).
- Select additional options and click “OK” to confirm deletion.
- Prefetch Files
- Open the Run dialog (press Windows Key + R).
- Type “%prefetch%” and press Enter.

- Cleaning Temporary Folder:
- Open the Run dialog (press Windows Key + R).
- Type “%temp%” and press Enter.
- A folder containing temporary files will open.
- Caution: Some programs might be using temporary files while you’re cleaning. You can close any unnecessary programs beforehand to avoid interrupting them.
- Press Ctrl + A to select all files and folders.
- Press Delete (Shift + Delete for a permanent deletion).
- You might see a prompt for certain files in use. In that case, skip those files and proceed with deleting the rest.
Remember: Restart your PC after cleaning up the files for the changes to take full effect.

Tips for Managing Startup Programs
Only disable programs you recognize and don’t need at startup such as Antivirus. Some programs are essential for system functions. Regularly review your startup programs. New software installations might add themselves to the startup list.
3. Disable Background Apps and Notifications
Background apps and frequent notifications can slow down your computer and disrupt your workflow. By managing these settings, you can improve your system’s performance and reduce distractions. Here’s how to disable background apps and unnecessary notifications in Windows 10 and Windows 11:

6. Speed Up Shutdown: Shorten App and Service Wait Times
Want your PC to shut down faster? You can adjust how long Windows waits for programs and services to close before forcing them to shut down. Here’s how to set it:
WARNING: Be cautious when modifying the registry. It can be risky. Consider creating a system restore point first.
- Service Wait Times
- Press Windows Key + R to open the Run dialog
- Type regedit and press Enter
- Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
- In the right pane, look for: WaitToKillServiceTimeout
- Create these values if they don’t exist (right-click -> New -> String Value)
- Double-click the value and enter 2000 in the “Value data” field
- App Wait Times
- Again Navigate to: HKEY_CURRENT_USER\Control Panel\Desktop
- In the right pane, look for: WaitToKillAppTimeout
- Create these values if they don’t exist (right-click -> New -> String Value)
- Double-click the value and enter 2000 in the “Value data” field
- Restart your PC for changes to take effect.
If you encounter issues, raise the wait times gradually until you find a good balance between speed and stability.
7. Run Windows Update
Keeping Windows up-to-date is essential for system stability. Updates often include fixes for known issues and vulnerabilities, including corrupted files. To run Windows Update:
- Go to Settings > Update & Security > Windows Update.
- Click “Check for updates” and install any available updates.
8. Check for Virus
Virus and malware programs can hog resources and slow down your operating system. Here’s how to fight back:
- Use Your Built-in Antivirus: Most operating systems come with built-in antivirus software. Run a thorough scan to check for threats.
- Consider Malwarebytes (Optional): If you want an extra layer of protection, Malwarebytes is a free scanning tool with a great reputation for finding malware. It can be a great second opinion after using your built-in antivirus software. (Note: We are not promoting Malwarebytes; this is for educational purposes only.)
By running a scan with either option, you can identify and remove any malware that might be slowing down your PC.
9. Perform a System Restore
Performing a System Restore to a point before the problems began can fix corrupted files. To perform a System Restore:
Access System Restore
- Windows 10
- Press the Windows key + S to open the search bar.
- Type “Create a restore point” and select the corresponding result from the Control Panel.
- Windows 11
- Click on the Start button and then on the Settings icon (gear symbol).
- Navigate to System > সম্পর্কে > System Protection.
Open System Restore
- In the System Properties window, go to the System Protection tab.
- Click the System Restore button. This will launch the System Restore wizard.
Choose a Restore Point
- Click Next to see a list of available restore points.
- Select a restore point that was created before the issues started occurring. You can click on Scan for affected programs to see which programs and drivers will be affected by the restore.
Confirm Your Restore Point
- After selecting a restore point, click Next.
- Review your selection and click Finish to start the restoration process.
Complete the System Restore
- Your computer will restart and the System Restore process will begin. This may take some time, so be patient.
- Once the process is complete, Windows will notify you whether the restore was successful.
10. Reinstall Windows
If all else fails and your system is still slow due to corrupted files, you may need to reinstall Windows. Maybe installing an older version of Windows (7/8/10) would be much more efficient if you consider installing one. Also, remember to back up your important files before doing anything.
Conclusion
Fixing corrupt files in Windows 10/11 is crucial for maintaining optimal system performance. By following these steps, you can identify and repair corrupted files, ultimately making your PC faster and more reliable. Regularly performing maintenance tasks like these can help keep your system running smoothly for years to come.
