Win7 64-bit Home Premium system forgot your password?

A colleague left, his computer set the password, but did not leave the password, our department's colleagues called me to re-install the system, I used to see, the colleague over there said, as long as the system can be entered into the password to clear the line, not necessarily to reload.

Such opportunities for me these rookie, is the best learning opportunities, so immediately Baidu, online tutorials a lot, but said basically is three ways, because there are Ubuntu 12.04 CD, so, I chose the simplest way.

One. Put the Ubuntu 12.04 CD into the optical drive, restart the computer, press the DELETE key, enter the BIOS, set the first boot device to boot from CDROM, save exit.

Two. To enter the installation interface of Ubuntu 12.04, press the keyboard up and DOWN ARROW keys, choose Try Ubuntu, press ENTER, is to try Ubuntu system, not the actual installation, if you want to install into the trial system after installation is also possible.

Three. After entering the Ubuntu 12.04 System, find the system disk of our win7 system (if you don't know how to find it, open a folder, flip it up), find windows->system32-> Osk.exe This file, cut it to the other disk first put (note Do not change this file to osk02.exe this kind of, so no, I personally tried); Find windows->system32-> Cmd.exe this file, change the Cmd.exe file name to Osk.exe

Four. Remove the disc, restart the system, enter the Win7 login screen, there is an icon in the lower left corner, click the Change icon, the "on-Screen Keyboard" tick, OK. The command Prompt window opens automatically, and the net user displays the user of the system, and then net User Ming 123456 (the administrator account displayed when Ming is net user, and the next 123456 is the new password for this account). After this operation, we can log in with Ming, the password is 123456. After entering the system, remember to change the Windows->system32->osk.exe file name back to Cmd.exe, and then move the original removed Osk.exe back on the line.

Haha, done, simple way!!!

But I haven't tried anything else on the internet, and I haven't figured out why I can change my password. The operation and maintenance of the road, a heavy and long way.
