Error after installing Windows Updates

I ran the Windows Update on my other computer, and when I
try to sign on to it, I get the following message:

A problem is preventing Windows from accurately checking
the license for this computer.
Error Code: 0x80004005.

I've gotten on using safe mode and uninstalled the
updates but I still can't get on. I've tried some of the
fixes listed for the same message, but different error
codes, and don't have any success.

Help!
