Forgot password in Windows Vista? How can I recorer?

I hope that wangjihong's answer had help you bro, if not, here is my suggestion. Option 1: Create a password reset disk Vista allows you to create a password reset disk which enables you to reset your password without much hassle. The problem with this option is that you have to create the reset disk before the password is lost. If you have many Windows machines where users logon locally, this might be a daunting task. Option 2: Get Petter Nordhal-Hagen’s NT Password & Registry Editor With this option you have to boot from a CD and then manipulate the SAM database. Manipulating the SAM database is always a bit risky. But if you have no password reset disk, this is the only way. Note that this tool comes without any warranty. I’ve been using it quite a few times on Windows 2000 and had never any problem with it, though. The latest version also supports Windows Vista. Option 3: Use miniPE xt, it works like option 2
