Solved Hidden Admin account password worked ONCE... never again

[zapp22]

gang I realize some of you are touchy about this subject but help me out - I have not seen this one before.
I bought [using it as 'we speak'] DC7900 from a huge recycler - the 3rd I've bought from these guys who do a great job. it has Windows 7 Pro on it from them [refurbisher volume licensing]. its activated, happy for the most part. their slipstreamed install process however sets a password on the Admin Account, and the password is "Administrator". last night I tried for the first time to get in there. the password failed.
this morning on a fresh start I tried again. Voila' - it began setting up the Administrator desktop [first run] so I turned to the important ritual of preparing my morning cup of Golden Yunan...
When I came back to the screen, it was sitting at the 'pick a user' screen again...:sarc:
I hit it, input 'Administrator' again, and it failed. again, and again and again so ....

is the account corrupted? I would really love to avoid a total nuke & reinstall if I can but if it must be, it must be. I am just wondering how this can happen. obviously its a security concern.

what started me on this path was there is a 'live' instance of 'Windows Mail' installed on the system that is invisible in the Programs Install/uninstall utility so I cannot get rid of it. when I try to delete any of the associated files I'm prevented. Try to change permissions, I'm prevented. thus ... you know the drill

Try a cold start again.

I dont think the Password would change its self.

Make sure you are typing it in correctly!

i treated it as though the Admin account was corrupted.
Trinity Rescue Kit has winpass and I used that to whack the password.

all is well now.
