How Cam I Remove Windows Administrator Password Without Logging And Without Format The System?

You can do it by reinstalling windows on your system but you should have to install a fresh copy of XP instead of formatting the whole drive. Don't give same path but give different path to the windows during installation. On the other hand, you can also install a fresh copy of XP on different drive.

How I can remove password of windows xp with out fresh installation

Iam forget my password

I have  downloaded Windows Password Recovery Tool 2.0. It not only supports XP, 2000, and NT, I have personally tested it with Vista Home Premium and Ultimate. It works perfectly to reset any local user account to a blank password. I Wrote it to an old 128mb USB flash drive do this. Booting up and clearing a password takes a minute or two works like a charm.
