Even though I am the person who is familar with computer in our household, My sister insists on maintaining her own Vista system, Fortunately, she does take my advice when she is unsure of necessary steps, and I was able to get her to use a Standare User account and then to provide the Adminstrator credentials as a security precaution
Because I am always talking about securoty and password, she recently hanged the Administrator password in oder to keep her system safe, Unfortunately, a few weeks later when she needed to make a change to her system, she realized that she completely forgot the new password. Of course, this snafu was now my problem to fix.
Now, being a very tech, I calmly assured her that everything was going to be fine. While she dose have a password reset disk for her user account, we never created one for the admin account.
Fortunately a friend recommend us to use “windows password key 8.0"( http://www.lostwindowspassword.com) to gain access to a system on which the Administrator account password was forgotten.
To my surprise, the software works very prefect, easy and simple to solved our problem.

Also, there are a lot of other ways to try, by the way, taday I will show you other if you want to use the security sofeware. I remember seeing a Microsofe Help and support article about being able to use system restore to gain access on whoch the administrator account password was forgotten.
Of course, in order for this technique to work, system restore must be enabled and there must be a recent point restore point during which you were able to successfully log on to the system.
Other, For security reasons, this method should only be used on a temporary basis. Your Administrator account should not be left enabled without a password. So, have a look around, but don't move in. And when you're done, I strongly urge you to re-enable your user account(s) and promptly disable the Administrator account.
If your goal in accessing the Administrator account is to ditch User Account Controls, a somewhat safer way to do that would be to stick with your account with computer-administrator privileges (the one that is not named Administrator). Open the User Account Control Panel. Click the link there that reads “Change security settings" (in Vista Beta 2) and “Turn User Account Control on or off" (in Build 5472 and beyond). On the subsequent screen, you'll find an easy way to turn off UAC.
Hope those above can help you to overcome a lost Administrator password.
