    Thanks. I already use this built in security features.

    So, here’s a question. When a user loses the usbkey, what do you do? Logic would dictate having a backup of the usbkey, however when you insert a different key it is assigned a different drive letter rendering the backup useless.

    Also with the microsoft support scan being so prevalent how can you reset the syskey once they’ve used it to lock you out? particulalrly hard to do on the uefi systems.

    How come when I type in ‘syskey’, I get a message from Windows that it can’t find ‘syskey’? I on Windows 10; is that not necessary, or built into Windows 10? I was just curious, because I know that Microsoft tech support scams use syskey, to lock users out of their own computers, so I was researching ways around that; of course, the BEST way around that, is to just hang up on them! lol

  5. Syskey.exe utility is no longer supported in Windows 10 v1709 and later.
