still stuck on password

Two questions.

One - when I was able to log on last week my username was my name and that was the only option to choose from. It never even showed "administrator". Does that mean there would have been no password set for it? Did it still exist if it wasn't showing up?


Two. I recently and accidentally deleted "system" and "admin.." from my registry files of some sort - by deleting this, would it affect the password at all when trying to do a recover of wnidows xp cd rom? I swear for the life of me, I knew the password, but it was for my username, like I said = (refer to frist question).

Thanks.
