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. All Windows Updates were installed. I have tried using a different administrator account, and it does not work.
A quick chkdsk
scan shows no errors.
A SFC scan now shows no errors.
I found the error log!
Why is the registry corrupt?
