If you have forgotten your Windows administrator password, the bottom line is that there are two ways to deal with the problem. The first is to use a specific password remembrance program, or to re-install Windows completely. Although the latter works every time, it will wipe your entire settings and files inside your PC, and is not recommended. Instead, I would recommend you use a program which is able to "reset" the password of your system, by deleting the stored information that it may have inside.
The way that software works to remove the Windows administrator password from your PC is to basically replace the files that will hold the password of your PC. More specifically, this works by Windows checking the information inside the files that have been stored against the input passwords that you've typed into your PC. The reason why you cannot log in is because the data you typed into your computer does not match with the stored passwords that are on your hard drive, meaning that if you can change the stored password settings on your system, then you'll be able to log in correctly again.
We've found that a program called "Password Resetter" works in the most effective way to fix the problems on your PC. This program basically works by making a CD that loads up before Windows. This then takes the files that contain your computer's password, and changes them so that no information is stored inside. This means as you restart your system, you'll be able to log in without the need to actually type the password in. This method is probably the safest and most effective way to get the administrator password off your system, allowing you to login as effectively as possible again. This tool is used by many PC repair companies to get rid of the stored password that's on your system, allowing your computer to run much smoother as a result.
