Reset password on Linux from GRUB
article #1076, updated 20 days ago

If you have access to the console and the machine runs GRUB or something similar, reset of a password is easy. Just interrupt the boot before kernel load (hit the Tab key if it really is GRUB you have there), edit the kernel load line, and add the following to the very end:

init=/bin/bash

Then boot that kernel load line (F10 in GRUB) and the machine will come up in single-user ‘bash’ shell, and you can run ‘passwd’.

Deletion and replacement of the user profile, eliminated the problem.

Advanced user/password/group window in Windows 7
article #235, updated 2462 days ago

It was “control userpasswords2” in XP.  Under Windows 7, put this in the start-button search box:

netplwiz

The box you want, will come right up.  This also handles auto-login if the machine is not attached to a domain.
