Windows command: "net user <name> <password>" does not work

Question

I forgot my user account Windows 7 Pro password and I am trying to reset it.

I don't have a reset password disk, unfortunately.

I did manage to obtain an admin cmd prompt, where I type:

net user

Windows says the command completed successfully, but

after I reboot, my new password still does not work.

I also tried

net user /passwordreq:no

again, completed successfully, and after reboot, still can't log in without a password.

Why doesn't "net user" work?

I can use

net user /add foobar

to get a new user and log in, so that means I do have a successful admin account prompt. Somehow it is only

net user

password functionality that does not seem to work.

Answer 1

OK that is really weird. Normally, to get

net user /add foobar

and other such commands, to work, I have to reboot the machine.

However, in the case of net user password functionality, it only works if I do not reboot the machine.
