Windows won't save password change

Hello fellow Windows 7ers,

I have just had this problem recently that has been very frustrating.

Preface this with: I had this OLD password that I had set. During this time I had that password I did use windows' system image utility to backup my old 500GB drive to restore it on a 1TB drive and I did that while I had this password.

Now, when I try to change the password it will not save the change. When I change it, I can logout and it will accept the NEW password, but once I reboot or shut down and it comes back up, it only accepts the OLD password.

Any ideas? Thanks

It sounds like windows is corrupt you may want to try reinstalling it to fix the problem

Yeah I know. That was my last resort. I think my users .dat file must be somehow messed up. I have since migrated my users stuff to a new one. So far so good. Still with I knew why windows did that.
