Hi experts, a friend of mine gave me his old unused Windows Vista computer a few months ago. I just went to do a normal reboot here a minute ago and by mistake clicked on the "Lock Computer" button that is right next to the reboot button. Now the thing says it's locked and me nor my buddy know the old password he used for it. So I'm stuck. I just left the screen as is and didn't touch anything. Can I just power off and power on and it should come back into normal mode? This computer never needs a password - whenever I reboot it just comes right up with no entering of a password required.
