This post will show you how to use the DISM Tool to repair a Windows System Image in Windows 10/8.1. The System Update and Readiness Tool or CheckSUR tool will scan your Windows computer for inconsistencies, which may be caused by various hardware failures or by software issues and potentially fix that corruption. In Windows 10/8 and Windows Server, the Inbox Corruption Repair brings the functionality of CheckSUR into Windows. You do not require a separate download to get the tool.

Windows Component Store Corrupt

Repair Windows System Image using DISM

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 corruptions, 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 it the corruption or image is repairable. If yes, then you can use the /RestoreHealth switch to fix the corruption.
