How to Reset Windows10 Password

1.  C: is which partition the Windows installation is on.First, you’ll need to create a bootable Windows 10 disk on a flash drive. 
2. Reboot your computer by using this flash drive. 
3. When you see the initial Windows 10 setup screen, press Shift + F10 to open a Command Prompt.
4. Type cd /d C:\Windows\System32 *** C: is which partition the Windows installation is on. It might be D: or E: ...etc. Remember, at my computer it was E: 
5. Type ren utilman.exe utilman.exe.bak
6. Type ren cmd.exe utilman.exe
7. Type wpeutil reboot
   ***The computer will be rebooted!
8. You will see he following screen. Click on the click the Ease of Access shortcut.

9- You’re into a command prompt, use the following line to enable the default Admin account.

net user Administrator /active:yes

10- One more time on the sign-in screen, and this time you should click the Administrator account in the bottom-left corner. There isn’t a password on this account, so it should sign you right in. Now, you can reset your own password.

Putting Everything Back

Once you’ve logged into your own account, you’re almost done! You just need to fix the shortcuts you changed and call it a day. Go ahead and reboot again using the Windows 10 installation disk you created earlier. Once the initial welcome screen loads, press Shift + F10 and navigate to C:\Windows\System32 as you did before.

Use these two commands to put the Ease of Access shortcut back as it was:

ren utilman.exe cmd.exe

ren utilman.exe.bak utilman.exe

Because the Admin account is a security risk, you should disable it here until you need it again. Type this to disable it:

net user Administrator /active:no

One more reboot, and you can get back to your normal computer usage! Feel free to type the following command  to reboot.

wpeutil reboot
