Sometimes you just need to get into some computer without knowing any passwords to that computer.
Now a days everything is so much easier than past so now you just have to burn yourself a Kon-Boot CD (or use USB dongle) and boot computer from that and
just press enter couple of times and windows starts.
Then you can log in with every username what somebody has used on that computer and who has profile without typing anykind of password.
You can find Kon-Boot here: http://www.piotrbania.com/all/kon-boot/
Or just download it here:

If you just want to reset administrator password you can always use old ntpasswd tool: http://home.eunet.no/pnordahl/ntpasswd/
So change your “Boot Sequence” and put your computer boot first from harddrive and then from CD/DVD/USB drive and protect your BIOS with password.
If you are using laptop you should probably think about using truecrypt to crypt your whole drive.

Super-Duper site! I am loving it!! Will come back again – taking you feeds also, Thanks.
is there any chance to do it without installing any software..?
thanks
You do bootable CD and boot that computer with that CD so you don’t have to install anything.
For some reason that software works pretty well with some computer and with some it doesn’t work at all… even that they should have same version of Windows XP or Windows 2000
