2 years without problems now windows says its not valid

I hope that someone will be able to answer this one.  I bought my dell computer with windows vista on it in June of ' 07.  About 3 days ago he did an automatic update of windows and now it says that is not validated.  It's never happened before.  Now I can't go in the control panel to change anything, the window will not just open.  It is as I have more administrative rights on my computer when I have the only account on it.  Tried to do validation on www.microsoft.com/genuine .  Installed the files which it said you and it will still not validated.  If no one can help me with this it would be great.
Thank you
Matt
