Windows 7 64 bit SP1 Problem

May I assume that you have done all this:

Reduce the size of the CBS.log with this command:

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log

Then right click on the cmd window > "Select All" and right click again on the highlighted area. Then it is on the clipboard and you can paste it here.

Please follow the Windows Update Posting Instructions and post the requested data - if the file is too large, either split it, or delete the older CBSPersist files, and try again

There's some interesting errors in the CBS.log background..

I think the problem is that the SoftwareDistribution folder is corrupted, the system is unable to update to the latest Update Agent as a result.
Hopefully, the solution will be to rename the folder, which will force Windows to rebuild it and re-download the update.


Open an Elevated Command Prompt
Run the following commands

NET STOP WUAUSERV
REN C:\WINDOWS\SoftwareDistribution SDOLD
NET START WUAUSERV

wait 15 minutes, and reboot
then wait 10 minutes, and open Windows Updates, and run a Check for Updates.

Install only the oldest update found - and reboot once installed
then go back to Windows updates and install the others.

Yep :)
