Windows Component Store Corrupt
How to Run DISM in Windows 11/10
You can repair Windows System Image using the DISM tool.
If a Windows image becomes unserviceable, you can use the Deployment Imaging and Servicing Management (DISM) tool to update the files and correct the problem. In the case of system inconsistencies and corruption, you can use the DISM tool by using the Cleanup-Image functionality along with these available switches.
Use Dism /Online /Cleanup-Image followed by these switches:
1] /ScanHealth
This checks for component store corruption and records that corruption to the C:\Windows\Logs\CBS\CBS.log but no corruption is fixed using this switch. This is useful for logging what, if any, corruption exists. Use:
Dism /Online /Cleanup-Image /ScanHealth
This could take 10-15 minutes.
2] /CheckHealth
This checks to see if a component corruption marker is already present in the registry. This is merely a way to see if corruption currently exists. Think of it as a read-only CHKDSK. Use:
Dism /Online /Cleanup-Image /CheckHealth
This could take less than a minute.
3] /RestoreHealth
This checks for component store corruption, records the corruption to C:\Windows\Logs\CBS\CBS.log and FIXES the corruption using Windows Update. Use:
Dism /Online /Cleanup-Image /RestoreHealth
This operation takes 15 mins or more, depending on the level of corruption.
To carry out these operations, you have to open an elevated Command Prompt. First, you have to check if there are corruptions and if the corruption or image is repairable. If yes, you can use the /RestoreHealth switch to fix the corruption.
TIP: Fix corrupted Windows Update system files using DISM Tool.
You can use this:
- If your System File Checker is corrupted or SFC is not working and the SFC /SCANNOW command is unable to repair corrupted system files because the store is corrupted.
- To fix Windows component store corruption when the same Windows Updates continue to appear to be available to install even though they already show successfully installed in update history.
- If a Windows image becomes unserviceable, you can use the Deployment Imaging and Servicing Management (DISM) tool to update the files, correct the problem, and repair the Windows image. You can use DISM to repair an offline Windows image in a WIM or VHD file or an online Windows image.
