Why can't I install Windows Vista security updates?
Code:8E5E0147 Windows has encountered an unknown error
I receive this everytime I try installing a security update. the only update I have been able to run since early December 2008 was a Windows Defender update which I was able to do a little while ago. this all happended about the time I loaded my Norton Antivirus software which I did turn off when trying to install these updates.
