Windows 8.1 update freezes

I ran sfc /scannow and it returns with:

"Windows Resource Protection found corrupt files but was unable to fix some of them..."

Here is a CBS.log View attachment CBS.zip

What should I do?

I'll check it out when I come home.

Okay. According to this line of text, you should've rebooted your pc.

Also, you should shut down your pc once in a while. According to this, you last booted up your computer on 7-19. 10 days ago. When the SFC /scannow was first run, it started 5 days from the last boot time.

Did the scan take 5 days? I'm thinking not. But I'll only know if you confirm it.

If you wanted to, you could run Dism.exe /Online /Cleanup-Image /RestoreHealth in an elevated command prompt to find those corrupted files. If it says that it found files and successfully repaired them, run sfc /scannow again. If you get the same "Windows Resource Protection found corrupt files but was unable to fix some of them..." result, then the problem is related to a buggy update Microsoft released. SFC finds the added .json files in the update(s) as corrupted because they're unreadable but DISM marks them as readable. If this is the case, you can leave it alone as there is no problem.

Actually just rebooted it the other night, weird that it said that but I rebooted it again anyway, trying the dism.exe now.

The reuqested operation failed. Do you need the DISM logs too?

I guess so. Also, are you experiencing any problems? Because they could be a false positive on both scans.

If by problems then you mean the original no update possible then yes still happening. Here's the DISM View attachment dism.log

I'm just trying to upgrade to W10, should I just reinstall 8.1 and then update?
