0x800f0831 - CBS_E_STORE_CORRUPTION after blackout.

[JohnLai]

Hi, I was installing windows10.0-kb4601382-x64_87d4ba1dac3ea12aee681b660c505607ae9b01f3 halfway (around 20 - 30%) when my area was hit with blackout.
I tried running SFCFix, but there is no error :


SFCFix version 3.0.2.1 by niemiro.
Start time: 2021-03-11 00:13:09.960
Microsoft Windows 10 Build 19042 - amd64
Not using a script file.




AutoAnalysis::
SUMMARY: No corruptions were detected.
AutoAnalysis:: directive completed successfully.




Successfully processed all directives.
SFCFix version 3.0.2.1 by niemiro has completed.
Currently storing 0 datablocks.
Finish time: 2021-03-11 00:20:26.838
----------------------EOF-----------------------


Apparently there is some "Store corruption, manifest missing for package" errors.
I had run DISM /Online /Cleanup-Image /RestoreHealth command with no luck.
The result for DISM is "The source files could not be found".

*Forgot to mentioi SFC /Scannow had been run, no luck either

Any help?

Just now, windows 10 automatically tried to install windows10.0-kb5000802-x64_f1da84b3bfa1c402d98dfb3815b1f81d7dceb001 (latest security update today)
Big failure. Same error 0x800f0831

(Ignore the previous log above)
Here is the new log on kb5000802.

Update:
Fixed it by doing a repair install via Windows20H2 iso and select keep all personal files and apps.

Then windows update seems to proceed smoothly.
