I upgraded to Windows Professional from Home Premium and everything was running fine for about 3 months. I added a domain user account (this is a work computer with a shared server) and have been logging in using this domain user account.
I needed to install some software so it asked for elevated permission...I tried to log back into the pc as an administrator/owner, using as the username "name-PC\local". The funny thing is when I put the known (this is written down and has been used several times) password, it kicked it back. At first I thought I was typing too fast or screwed something up but it denied the password repeatedly and I still can't get in.
I read that it's possible for the OS to corrupt so I put the upgrade disk back in the computer and ran it after shutting it down. It just moves into Windows 7 normally and doesn't offer me the option to do a System Restore to when my admin password was working.
Any advice that anyone could give would be very useful. I'm so frustrated because I need to install these programs to move forward with a project and I'm wasting time with this hassle.
