I forgot the Windows 7 password on my own computer, I used the trick described in Resetting Your Forgotten Windows Password (http://www.howtogeek.com/96630/how-to-reset-your-forgotten-windows-password-the-easy-way/):
Boot from the Windows 7 repair ISO.
copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe Use the Sticky Keys feature of the log in screen (now the command prompt) to execute:
net user Admin MyNewPassword I kept the file there in case I ever forgot it again.
A client of mine asked if I could do the same for him, and he also has a PC with Windows 7 Professional x32.
I followed the same steps as on my computer. The command of step 2 says it was successful, but when press Shift five times to trigger Sticky Keys, the regular message for sethc.exe opens up.
I tried entering the command of step 3 directly from the repair ISO. This claimed to be successful as well, but the password was not changed!
What I'm doing wrong?
I have realized the problem is bigger than just not being able to change the password, any changes made to files using CMD don't actually change... and I can't figure out why.
In regard to the password, I tried using several "password reset" ISOs and they also look like they work but don't actually change anything.
