1, forget the password, but has logged into the system. This is easier to solve, first enter "Mmc.exe" in the search box in the Start menu, or press and hold Win+r, open the Run window input "Mmc.exe" and click OK to enter the console. Open file-Add/Remove Snap-in, locate local users and groups in the available snap-in on the left, click Add-Finish, and then click OK. Expand Local Users and groups in the Console root node, select Users, right-click on the right-hand user name, set password, and do not enter the original password. 2, forget the password, unable to log in the system. This situation is more troublesome to deal with, I tried safe mode, Win7 system disk repair, login WinPE, but can not modify the system files, it seems that the previous vista that method can not be used. And my method is similar to logging in to the WinPE modify file method. You need an Ubuntu installation CD (attached below), select CD-ROM to launch, go to the Ubuntu installation screen, select a language, and then go to the first "try Ubuntu without changing ...". Next wait to load the file, the time will be slightly longer, after entering the desktop, open the Win7 X:\windows\system32 folder, the "Osk.exe" here to cut to another location, "cmd.exe" renamed to "Osk.exe" and then re-boot from the hard disk. To the Win7 login window, click on the "Easy access" icon in the lower-left corner of the screen, then tick "Start Screen Keyboard" in the pop-up window and click "OK", at which point the command prompt is started. The rest is very simple, enter the command "NET user" to view the user name, and then enter the command "NET user username new password" (note the space). Finally, turn off the command Prompt window, enter the new password just set in the Login password box, and see if it is successfully entered the system!
