When you run the command net user username where username is the logon name
for your user account it show the account is active. You can enter cmd.exe
in the run box and then hit OK to open a command window if you are unsure of
how to do that. Below is what the output of that command should show. If the
administrator account is not active then you need to boot into Safe Mode to
logon and use it assuming you know the password which may be blank. In XP
Home you can only logon to the built in administrator account in Safe Mode.
If you can not logon as any administrator account then proceed as explained
in the link below which has pretty good instructions on a couple of ways to
help you do what is needed to gain access to your operating system again
including uploading your password hashes to a website that will attempt to
crack them for you.
