Win7 Home Password disaster

New computer Win 7 home premium. Only 1 user but log in window made me "choose" 1 user. So I changed setting to choose me to login automatically. Did this by going to controluserpasswords2 and changing setting to require user name and password. With only 1 user name in the list it defaulted to me. However, Trouble is I left password space blank because I wanted that security (I originally set a login password) Windows 7 "allowed" blank password but now on boot up, it goes straight to my account but neither the original password or "blank" work.

I tried NT Password and registry freeware and it worked up to a point. Set admin to no password but it wouldn't let me change the other password since it said was blank.

NT program says I have 3 accounts: admin, owner and guest. I can only work on the Admin and blank that password. NT program won't let me change anything on owner and guest because it says values are blank

When computer boots up it goes to account George account (my name) and won't accept any passwords. Tried switch user and says Administrator account is disabled. Going to George account kind of odd because George account doesn't even exist on the list of accounts shown by NT Password Registor program.

So somehow Win 7 boots up, and I guess goes into admin account (password blanked somehow --- did this fwiw even before I ran NT password Registry program). Then chooses George account (not listed by NT program) and neither my original password or the blank password work. So I can't boot up into win 7.

Any help would be sincerely appreciated!

This works for Vista & Windows 7.

Thanks theog. Away from my broken computer for the holidays, but will try your suggestions in the next day or two.

Still a little concerned that the NT Password and REgistry editor only found the default accounts (Admin, Owner and Guest) whereas the signin on Login had my name as the only available account. So a little confused where these different accounts are kept. Anyway, will give it a try and let you know.

Thanks again.

Thanks theog

Followed the instructions to make system recovery disc.

Ran the program and it actually offered me a chance to do a system restore before doing the registry edit. Figured that couldn't hurt.

During the restore, it said it found an error and corrected it. Afterward computer booted up fine. In fact went straight to the named sign in window (which is what I was trying to do originally because it made me select from 1 user, namely me). Old password worked and everything fine now.

So I guess Windows has a way to correct the password glitch. Too bad it didn't prevent me from making the error!

Thanks for your help,
