Malfunctioning update services, corrupted or missing system files, disk errors like bad sectors, and insufficient disk space can all prevent the system from completing the clean-up. Corrupted files can cause the system to get stuck at ‘Cleaning up 0/100% complete’ or show Windows update errors. Clearing the SoftwareDistribution or Windows.old folder usually resolves this issue, but reboot Windows in safe mode first. A quick fix is to restart your computer using the power button. Press and hold the Power button until the system shuts down, then press the Power button again. Only do this if you’ve waited more than 4-5 hours. If the issue persists after restarting, try the methods below.
1. Run Windows in Safe Mode
Safe Mode is a diagnostic mode of Windows. When you boot in Safe Mode, it starts with essential systems and services, which can help troubleshoot and fix issues that aren’t apparent when Windows runs normally. Safe Mode disables non-essential drivers and startup programs that could be causing conflicts or preventing clean-up.
2. Clear the SoftwareDistribution Folder
The SoftwareDistribution folder stores Windows update files. If these files are corrupted, Disk Cleanup may struggle to delete them, causing the system to get stuck at 100%. Manually deleting these files should resolve the issue.
3. Delete the Windows.old Folder
The Windows.old folder contains files related to Windows updates. Clear this folder if the issue persists after clearing the SoftwareDistribution folder.
4. Perform Disk Cleanup
Disk errors or insufficient disk space can also cause issues. Perform a disk cleanup and check the disk for errors to resolve this.
