So, I'm trying to update Windows 8 to Windows 8.1 via the Windows Store, but every time I attempt to, the update downloads properly, but then I get the error:

Windows 8.1
This app wasn't installed - view details

When I click on it, it says:

Something happened and the Windows 8.1 could not be installed. Please try again. Error code: 0x80070004
Try again Cancel Install

What does this mean? A quick Google search yields nothing.

I have tried rebooting, clearing the store cache, and resetting Windows Update.


A quick chkdsk scan shows no errors.


A SFC scan shows that there are many issues.

Could this be the issue?


I found the error log!

Why is the registry corrupt?
