Windows 8/8.1 Password Reset with a Windows 8/8.1 DVD and CMD

Today I'd like to share what I have learned in a in a sticky situation.I was busy with a customer's laptop and it turned off due to a low battery. When I turned it back on after connecting the charger, I discovered the laptop had a password, which I forgot to ask the customer for. So, following procedure, I called the customer and there was no answer.A few days went by trying to call the customer daily, but to no avail. I decided to try to reset the password on the laptop, which was running windows 8.1. My co-workers told me that the only way to fix this problem is to backup data, format and reload the laptop because it's impossible to reset a Windows 8 password.Being my hard headed self, I decided to do some research and came across a few exploits in Windows 8 and 8.1 (it can also work on windows 10, with a few tweaks). This is what I did:

1. Insert the Windows 8 boot disk into the DVD ROM and restart your system.
2. Boot into the BIOS, disable the secure boot and/or swap UEFI bios to legacy.
3. Set boot order for the DVD drive first and proceed to save and exit the BIOS.
4. When booted from the disc, select your language and click next.
5. Select Repair your computer and then click on troubleshoot.
6. Select command prompt and let the console open.
7. In the command prompt, you'll then see "X:windowssystem32>"
8. Type c: and hit enter, then type cd windows and hit enter again.
9. Type cd system32 and hit enter. You will then see C:WindowsSystem32>
10. Type copy cmd.exe cmd.exe.cmd2 and hit enter. It will then say 1 file copied.
11. Type copy Utilman.exe Utilman.exe.Utilman2 and hit enter.
12. Then Type ren cmd.exe Utilman.exe and hit enter
13. After that, type exit and restart.
14. Once booted into windows again you'll see the screen asking for a password. At the bottom left of your screen, you'll see an ease of access symbol. Click it and the Command prompt will now show up with admin rights.
15. Type net user and hit enter. It will display the account names.
16. Type net user (without the arrows) and hit enter.
17. Now type the new password (or leave blank) and hit enter and confirm the password and hit enter.
18. Restart your system and at the user selection screen type in your new password (if you selected one) and hit enter.

 Well done! You've now reset your Windows 8 and 8.1 password.GEEK IT 'TILL IT MHz ;)
