How to Use DISM to Fix Component Store Corruption in Windows 8.1?

DISM is the acronym of Deployment Imaging and Management which is a tool to detect corrupted system files and rectify the problem. Suppose, if problem occurs in Windows component store where neither SFC/SCANNOW command is able to sort it, nor does the update history shows correct result, DISM is used. In the ancestral versions, the system update tools was System Update and Readiness Tool (KB947821) which is also known as CheckSUR. This was replaced in Windows 8 and Windows Server 2012 by Inbox Corruption Repair. This cleaning process is exposed both automatically as well as manually. In the former process, the fixing of corrupted system files is accomplished without notice of end users and packages are re installed silently. The latter option is manual and is known as DISM/Cleanup-Image functionality.

This procedure worked. I have tried running sfc /scannow. It did find some problems with some of the System Files, but did not repair them.
After running your procedure listed above I ran sfc /scannow again and it now reports “Verification Complete 100%.
I was going to to a complete Windows 8.1 reinstall, but now I will not have to.

Hi Joe, nice to hear that your issue has been fixed.
