Unable to install update KB2676562, error 800B0100
I have not been able to successfully install updates KB2676562 or 2679255. And now, along with those, KB2709715 and KB2731847 fail to install.
I have tried multiple fixes:
1. MS Fix It and hot fixes
2. manually installed updates
2. Ran Chkdsk (no errors found)
3. Ran System File Checker tool
4. Reset the Catroot2 folder
5. Regsitered the Windows update files
6. ReNamed the SoftwareDistribution folder
7. Cleared the BITS queue
and 8. Ran the System Update Readiness toll (CheckSur.exe). This is the only thing that has defined a problem. It found the CBS Mum Corrupt 0x800F0900 and the CBS Catalog Corrupt 0x800B0100 and notes 4 unavailable repair files.
Any thoughts on if the CBS corrupt Mum and Catalog are causing the failed updates and how do repair those?
