I lost the Administrator password and do not have any other account. How can I get into my Windows installation, reset the admin password and create new user accounts?

Get ophcrack and boot up with that CD, you will get it very quickly.

I hope this can help you.last month my sister meet the same problem,and then we solved it as follow.There is a way to reset the password and it doesn't involve reformatting and reunstalling Windows. The solution is called Windows Password Key 8.0. It is the most popular and safe solution for resetting your Windows password until now.

Its better to use ophcrack!
download the CD image file from here
DOWNLOAD NOW
and then burn it on a Cd then run your PC with this disk, make sure before running, your First Boot Device is a CD/DVD Drive.

Boot your pc using Hirens and then search the net the crack software somethin' bout forgotten admin password. and then when you already downloaded it save it into a Flash Drive and then. . .
follow the instructions about the software and tada! you got your password back. . .

I am wondering if you can access safe mode on your pc. if yes, boot your pc and press F8 for advance startup options. choose safe mode. control panel, open computer management in administrative tools. in the left pane of the window, click local users and groups, click on users. right click the user whose password u want to reset. click on set password, a pop up appears but ignore it or if u like read. click on proceed. restart.
Actually, this works perfectly for xp. I hope it works for vista as well.
