Windows 11 system updates retain a large amount of cached files and old system version files locally, which can accumulate over time and occupy dozens of gigabytes of disk space. This can lead to insufficient system drive space and reduced operating efficiency. This tutorial will introduce several safe methods to clean these files, including using the Disk Cleanup tool, deleting temporary files through Storage settings, and using Command Prompt for advanced cleanup commands. Before performing any cleanup operations, it is strongly recommended to create a complete system backup using tools like Hasleo Backup Suite to ensure data security.

Method A: Stop Services and Delete Cache
This method fixes update failures, stuck updates, or error codes caused by corrupted cache by resetting the core cache folders of Windows Update. It is recommended to use this method only when encountering update issues, not for routine cleanup. (Suitable for advanced users)
📌 Operation Steps:
Step 1. Run Command Prompt as Administrator: Right-click the "Start" button and select "Terminal (Administrator)" or "Command Prompt (Administrator)". Click "Yes" if prompted by User Account Control (UAC).
Step 2. Stop related services: In the Command Prompt window, type the following commands one at a time. Press Enter after each command and wait for the "Service successfully stopped" confirmation before proceeding to the next.
net stop wuauserv
net stop cryptsvc
net stop bits
net stop msiserver
Step 3. Execute the following commands to rename cache folders one by one:
ren %windir%\SoftwareDistribution SoftwareDistribution.old
ren %windir%\System32\catroot2 catroot2.old
💡Tips: If the system drive is not C:, please replace C: with the corresponding drive letter.
Step 4. Execute the following commands to restart the stopped services one by one:
net start wuauserv
net start cryptsvc
net start bits
net start msiserver
Step 5. Close Command Prompt, then restart the computer.
Step 6. After restarting, if Windows Update functions normally, you can manually delete the C:\Windows\SoftwareDistribution.old and C:\Windows\System32\catroot2.old folders to free up space.
💡Tips: If you get permission denied errors when deleting, try again after restarting.
Method B: Use DISM Commands to Clean Component Store
This method thoroughly cleans update cache and repairs system components through command-line tools. Suitable for advanced users or when standard troubleshooting fails.
📌 Operation Steps:
Step 1. Run Command Prompt as Administrator: Right-click the "Start" button and select "Terminal (Administrator)" or "Command Prompt (Administrator)". Click "Yes" if prompted by User Account Control (UAC).
Step 2. (Optional) Execute the following command to check component status:
DISM /Online /Cleanup-Image /CheckHealth
If corruption is detected, run /ScanHealth for detailed scanning, then use /RestoreHealth to repair.
Step 3. Execute the following command to clean update cache:
DISM /Online /Cleanup-Image /StartComponentCleanup
Step 4. (Optional but Critical Warning) The following command will permanently and irreversibly remove old component versions.
DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase
💡Tips: This operation will delete all backups of old update components, making installed updates uninstallable. Only use when you are sure you don't need to roll back updates and urgently need disk space.
