Hi there

I have a problem when I want to run Windows Update, it starts downloading and installing the updates but 2/3 of the way it fails all updates with error code 800736B3. I tried to do a manual update on Service Pack 1 but I get an error also 2/3 of the way : ERROR_SXS_ASSEMBLY_NOT_FOUND (0x800736b3). I tried installing the updates 1 by 1 but still the same error no matter what the update. I also found that there is Kernel panic in the log.

I also did a sfc /scannow but no luck. I tried to do a Windows repair with the installation disk by selecting "Upgrade" in the installation menu but that also doesn't fix my problem. I did a virus scan using Microsoft Essentials and had no luck. I also did a scan in Safe Mode with Networking using http://onecare.live.com/site/en-us/center/howsafe.htm which I found in another forum suggesting that it might be a hijackware infection but again no luck. I ran a Windows Fix It which I found on http://support.microsoft.com/kb/KB971058. I also tried the Windows Update troubleshooter. The Firewall and Essentials is turned off. I ran the fix on http://answers.microsoft.com/en-us/...stalling/735140b2-ce4b-e011-8dfc-68b599b31bf5 which is the SFC SCAN and running the system update readiness tool but also no luck.

Reloading Windows is not an option.
 
Thanks AstroTurf but that was one of the first solutions I tried, that's where I got the Windows Fix Me from and the Windows Update troubleshooter solution.
 
Try a registry repair tool?

Why is a reload not an option?

Backup, format, reload, going to take about a hour.
