After I had installed Windows 10, I restored some backup files I had from another computer using Windows 7. When I tried to access the files, I was told that none of my software could load the files. After doing some research on several of the Windows forums, I found out the account I had been using from the very beginning was not the "real" Administrator account. As such, I could not change any of the User Privileges. Research again indicated I needed to "activate" the EUC Administrator, which I did. However, I was never asked for a Password when it was activated. Now, when I try to access the new Administrator account, I can't get past the Logon screen as I do not have a password. I have tried ALL the passwords I can remember from both the current Windows 7 and 10 User/Administrator accounts on this and the other computer, all to no avail. HOW do I either determine what the "default" password is or how do I change the "default" password without knowing what is in the system right now? Thank you.
