I lost my password a few weeks ago. i tried using recovery softwares, but I found out I couldn't disable "Secure Mode", so it didn't work. So I plugged in a Win 7 installation USB that I had, and opened the CMD from there. I renamed utilman.exe with utilman1.exe, and cmd.exe with utilman.exe. I rebooted the computer and pressed the ease of access button, but CMD didn't open. So I plugged in the Win 7 installation USB and tried opening CMD again, to realize thatit won't open since I renamed it. I tried installing WIN 7, but the installation didn't even start and gave me a "couldn't open <some file>" error. I'm guessing this is because I renamed the CMD. So I'm stuck in the middle of no where. The password I lost belongs tho the admin account, and it's the only one on that computer.
So am I forced to add another HDD with pre-installed windows? I don't want to lose any data since I am a game developer and I have a lot of files.
