I finally decided to make a thread after fighting with this problem for very long.

First, let's see what i have in the registry: Registry editor

Second, I have these pending updates: Updates

What i try to do now, is: update my computer :o

The problem is that when i restart my computer to finish the installation, i will reach the point saying 98% completed (or something similar), then it completes i think, but it says: reverting updates.

When i boot up again, i went to the event log, to find these errors: Windows error log viewer

.net Framework 3.5 is enabled in windows features. I suspect it might have something to do with my boot, i have a different boot record than windows'

Can you install all the other updates besides KB2795944? Have you tried installing it manually? – Ƭᴇcʜιᴇ007 Feb 17 '13 at 16:12
they all return the same error – Abdullah Gheith Feb 17 '13 at 18:19
zip and upload the folder C:\Windows\logs\CBS (copy the folder first to the desktop) and post a link here. – magicandre1981 Feb 17 '13 at 19:47
So what i did: deleted the content of CBS, tried to update again, got the error again and uploaded the logs (so that you would have a fresh log without too much irrelevant stuff): – Abdullah Gheith Feb 17 '13 at 22:05

Use boot recovery option to repair the BCD store. Also make sure the 350MB partition which contains the bootloader is not full.

Thank you, that seemed to solve some of the problem i guess. But windows update is still not working properly, The only missing update is now this one: KB2770816 – Abdullah Gheith Feb 22 '13 at 2:30
To answer myself, according to this site: the cause of that error is an entry in the registry db. I tried creating it myself but i couldn't, regedit said it already existed even though it didn't. I downloaded a software called: Registrar Registry Manager. Then created the entry, and it updated like a charm! Again, thank you magicandre, you certainly are magic :p I looked in the log myself but didn't see that. – Abdullah Gheith Feb 22 '13 at 2:44
nice to hear that the issue is fixed :) – magicandre1981 Feb 22 '13 at 4:51

I have had the same issue.

After uninstallation of IObit Start menu 8 the Windows Update are working.
