How can someone get into a laptop with Windows 2000 without the username or the password?

To enter in Windows 2000 terminal without a username and a passWord you need:

1. exclusive physical access it. 2. Windows 2000 Installation Disk.

Follow these steps:

1. Boot the system using the Win2000 Bootable Disk. 2. Goto the Recovery Console. 3. Presto.

Since Win2000 does not ask for an Administrators PassWord in the RC; now you should be able to have DOS based access to your files.

P.S. This I have tried on a Desktop System; you may try it on your laptop ;-)
