An unauthorized change was made to Windows. Error 0x004D401

windows vista pro 32 bit.  Just restored the os, and says it is legal when I look it up.

this error message keeps coming up.    An unauthorized change was made to Windows. Error 0x004D401.

in pervious problems I finally disabled the control panel and did not get updates.  everything worked fine before this.

Visit and click on Validate Windows, then restart your computer.

there was no validate windows link on this site.  Am I looking at the wrong place?

Sorry for the delay.

Went to the url and that worked, when I went to enter the code given, it said url cannot be found.  But since then we have had no problem.  I don't think that is supposed to work that way, or am I wrong.



If that works out that is all I had to do.
