Help needed with password in CMD.com

Help me. I was messing around in dos yesterday, and when I booted my pc this morning, I found that I had changed one of my users passwords through net user. I would have just normally clicked on the Icon and logged in, but now I need a password to log in. Is there some way that I can use net user to get rid of the password and log back in? :confused:

Did you set a password on the administrator account ? If not, boot into safe mode and remove the password ? i think you can do that !

thanks, that worked out for me, I got it fixed now.
