That is, leave it blank and click ok.
There is a long discussion in this forum about the dangers of having just one Admin capable account, and even moreso where people try to (and succeed!) to get XP down to just one account.
Even if you can't logon, there are ways to get at the data files if you don't use EFS (please don't use that!)
Again, try no password and then try your old username and password to logon.

Hi, if anyone knows anything about this, please help, I am desperate. I downloaded TweakUI (XP PowerToy), and I went to Logon and I unchecked 'Show Username on Windows Screen.' After I restarted the computer, it would not let me log on, the username changed from my name to Administrator and asked for a password for that. I'm on my second computer and I'm trying to find out anyway to solve this problem and let me log back on. I tried restarting it in Safe Mode, it did not work.
Please help...
