First off, I'm not a shill for any software company. I ran across this software and it seems pretty decent.
I had a laptop that someone brought back to me a few months after they left the company. The dumb a$$ changed the administrator password on me, the laptop had long been removed from the domain and was setting around to be deployed.
I booted up my Easy2Boot USB stick and tried to use to use good old PassPass, but it doesn't work on Win 10 1809 64bit. My old copy of KonBoot also failed me. So I farted around and finally used Easy2Boot with Win 10 PE to backup the sethc.exe file, copy the cmd.exe to sethc.exe on the laptops Windows\System32 folder, rebooted to the OS and stabbed the SHIFT key 5 times at the logon dialog. The 5 shifts brings up the 'sticky keys' feature, only by swapping the file it brought up a cmd window instead of sticky keys. I changed the password at the command prompt and Robert's your mother's brother. I had to boot back to PE to swap the correct sethc.exe file afterwards.
I had not had a locked administrator account in a long time, times previous it was still on the domain, so I used my domain admin account to log on and change it, The sticky keys hack works but I really missed the simplicity of PassPass or KonBoot. While hunting around and seeing what else was out there I came across a program called PCUnlocker. I hesitated, but it was pretty reasonably priced, especially if you Google up a coupon for it. I got the Enterprise version for less than $30. And it works great. Boot to it, select the account and click change password.
I put the original ISO file on my Easy2Boot drive. Then made a .imgPTN file and put it on it too, so I can use it for MBR/Legacy mode and EFI boot both. Supposed to work with server editions too.
