I have two pcs Windows 8.1pro and Win7 pro. I have two users on these pcs, first user named "admin", and second user named "John". They both have administrator rights, that way John can use the pc without restriction - "installing apps ect..". Is there a way I can protect user "admin" password from being able to be change by the other user ? We had an incident where John left the company, and he knew enough to change both passwords. We were able to get back in using other password utility to unlock, but I am wondering if there is another way. Thanks in advance.
