windows 8.1 - Can dism /restorehealth be used to restore from a mounted 8.1 ISO?

On my x64 Lenovo z580 laptop with Windows 8.1 x64, I was trying to install KB2919355 when I encountered the error 80073712 which translates to component store corruption.

Since then, I have run the following commands copied here with results:

1. sfc /scannow - result: no integrity violation


2. dism /online /cleanup-image /checkhealth - component store is repairable


3. dism /online /cleanup-image /scanhealth - component store is repairable


4. dism /online /cleanup-image /analyzecomponentstore component store cleanup recommended: Yes


5. dism /online /cleanup-image /restorehealth dism failed to perform any operation. Either the source is invalid or componentstore is not
   repairable Error code: 800f081f

Previously, I had upgraded to 8.1 using Windows Update. Now, I have downloaded the 8.1 ISO from here

Question: If I mount the 8.1 ISO to drive H:, Can I use the dism /online /cleanup-image /restorehealth /source:H:\sources\sxs /LimitAccess to repair my componentstore?

Answer

That error message is due to an issue with Windows Update. The DISM /online command uses Windows Update for it's file source. The article for KB 957310 should help you to resolve that error message, and then the DISM /online command should work fine once again.

Hope this helps,
