Windows 8 and 8.1
This is the response I get when I run the Windows update troubleshooter from the Windows 8.1 Action Center. If I click next it reports the errors have been fixed. However if I run it again it reports exactly the same errors.
After searching the Internet I have found that several users have reported having this issue. As result of the aforementioned search I have tried the following:
1) Run the Fixit tool for Windows 8.1 located at: http://support.microsoft.com/kb/971058/en-us.
2) Run the System Update Readiness commands: DISM.exe /Online /Cleanup-image /Scanhealth and DISM.exe /Online /Cleanup-image /Restorehealth located at: http://support.microsoft.com/kb/947821/en-us.
3) Saved contents of C:\Windows\System32\catroot2 to a temp folder and then deleted contents of C:\Windows\System32\catroot2.
4)Renamed C:\Windows\SoftwareDistribution to C:\Windows\SoftwareDistribution.old
5) Restarted Windows 8.1.
6) Verified that C:\Windows\System32\catroot2 and that C:Windows\SoftwareDistribution folders had been rebuilt.
7) I then ran the Windows update troubleshooter from the Window 8.1 Action Center again and got the same response as listed above. The errors still exist and are not fixed.
8) Finally, I did a completely new clean install of Windows 8.1 and without installing anything else (no updates, no software, no antivirus) the above errors appeared within an hour of the install.
Any suggestions that will help fix this issue will be of great help.
