Type NTPASSWD at google.com and now you find the free tool to set that password for the accounts.
This should let you back in, at least to the point that the OS is damaged or not.
I have an HP laptop running XP Pro. I started having problems with windows locking up and the only way to unlock it was to power down. When I power up I get the CHK DSK screen and it would get through the first stage and then hang up at 27% of the second stage. If I skipped the CHK DSK screen I could get it to boot up, enter my password and then work a bit til it froze again. I thought there might be a virus so I ran my AV software but that locked up also. It seemed that as long as I didn't tax the system too much it would work but as soon as I opened more than one document or another program it would hang.
I thought maybe starting in safe mode would help so I selected that option in the boot menu of msconfig. Now it boots up in safe mode but won't recogognize my password. I am using the same one I used in normal windows and it doesn't work - I checked Caps lock and tried all different variations of my password but it won't work.
In working with HP tech support they said the HD is toast and sent a new one but there are a few files I want to get off this one prior to sending it back - if I can get back to normal windows then I think I can get to the files but I can't get it to start up in anything other than safe mode - even going to F8 and selecting 'Start windows normally' option.
Any suggestions as to how to either get rid of the password or get it to stop booting in safe mode?
