Windows Updates fail 15AUG2012 - (KB2732500) (KB2729094) (KB2732487) (KB2647753) [Error 80071A90]

myrddin55 asked on
This morning's updates will not install correctly. After the restart system button the installation fails to complete during boot up and 'reverts' to previous. When the system restarts the update window shows the updates as outstanding which then becomes a reiterative process. Can you help please - I've tried the fix-it man but no good so far! As a consequence of these update failures my AV software (ESET NOD32) displays a constant warning.

KB2647753 was the offending update for me. Install this one on it's own, the rest should then all run through fine.

Try installing KB2647753 using the link below:


This updates registry entries after reboot and prior to login.


After restarting for the above install you should be able to install the remaining 3 updates.


If necessary, install KB2729094 from Windows Updates separate from the remaining 2 (KB2732487 and KB2732500) updates.


I hope this helps.
