Disk Cleanup is a built-in Windows utility that helps free up storage space by removing temporary files, system logs, cached updates, and other unnecessary data. It is commonly used to maintain system performance and reclaim disk space on Windows 11 computers.
However, some users encounter issues where Disk Cleanup does not open, freezes during scanning, fails to delete files, or crashes unexpectedly. These problems are usually caused by corrupted temporary files, system file damage, Windows update cache issues, or disk-related errors.
If Disk Cleanup is not working in Windows 11, follow the troubleshooting methods below.
How to Fix Disk Cleanup Not Working in Windows 11
Work through the following solutions in order. After completing each step, try running Disk Cleanup again.
1. Restart Your PC
Temporary system glitches may prevent Disk Cleanup from functioning properly.
- Save your work and close all applications.
- Press Windows + X.
- Select Shut down or sign out > Restart.
- After restarting, search for Disk Cleanup and run it again.
Restarting refreshes system processes and clears temporary conflicts.
2. Run Disk Cleanup Using the Run Command
Sometimes the tool may fail to open from the Start menu.
- Press Windows + R.
- Type:
cleanmgr - Press Enter.
- Select the drive you want to clean (usually C:).
- Click OK.
This launches Disk Cleanup directly.
3. Run Disk Cleanup as Administrator
Some cleanup operations require administrative permissions.
- Press Windows + S.
- Search for Disk Cleanup.
- Right-click it and select Run as administrator.
- Choose the system drive and allow the scan to complete.
Administrator access allows the tool to remove system files.
4. Delete Temporary Files Manually
Excessive temporary files can cause Disk Cleanup to freeze.
- Press Windows + R.
- Type:
%temp% - Press Enter.
- Select all files in the folder (Ctrl + A).
- Press Delete.
You can also repeat the process using:
temp
and
prefetch
folders.
5. Run System File Checker (SFC)
Corrupted system files may cause Disk Cleanup to malfunction.
- Press Windows + S and search for Command Prompt.
- Right-click it and select Run as administrator.
- Enter:
sfc /scannow - Press Enter and wait for the scan to finish.
- Restart your PC.
Windows will repair damaged system files automatically.
6. Run DISM Scan
If SFC does not resolve the issue, run a DISM repair.
- Open Command Prompt as administrator.
- Run the following command:
DISM /Online /Cleanup-Image /RestoreHealth - Wait for the process to complete.
- Restart your PC.
This repairs deeper Windows image corruption.
7. Clear Windows Update Cache
Windows update files can interfere with Disk Cleanup.
- Press Windows + R.
- Type:
services.msc - Press Enter.
- Locate Windows Update.
- Right-click and select Stop.
- Navigate to:
C:\Windows\SoftwareDistribution - Delete the contents of the folder.
- Restart the Windows Update service.
Afterward, try running Disk Cleanup again.
8. Check Disk for Errors
Disk errors may cause Disk Cleanup to fail.
- Press Windows + S and search for Command Prompt.
- Run it as administrator.
- Enter:
chkdsk C: /f - Press Enter.
- Restart your PC if prompted.
This scans the drive and fixes file system errors.
9. Use Storage Sense as an Alternative
If Disk Cleanup continues to fail, you can use Storage Sense.
- Press Windows + I.
- Go to System > Storage.
- Enable Storage Sense.
- Click Temporary files.
- Select the files you want to remove.
- Click Remove files.
Storage Sense performs similar cleanup tasks.
10. Install Windows Updates
Outdated Windows builds may cause system tool issues.
- Press Windows + I.
- Go to Windows Update.
- Click Check for updates.
- Install available updates.
- Restart your PC.
Updates often resolve built-in tool problems.
Conclusion
If Disk Cleanup is not working in Windows 11, the issue is typically caused by temporary file corruption, system file damage, disk errors, or Windows update cache problems. In most cases, clearing temporary files and repairing system files using SFC and DISM resolves the issue quickly.
By following the troubleshooting steps above, you should be able to restore Disk Cleanup functionality and free up disk space on your Windows 11 system without further issues.
