The Bones of the Matter

Gadget doesn't like anyone nosing around his computer when he pops out for a quick sniff around the neighbourhood. So, if you're popping away from your desk and don't want anyone snooping around your PC, hit the Windows key and "L" together which will lock the desktop. No one will be able to gain access to your PC unless they know your password.

Gadget is careful to make sure no one knows that his password is 'marrowbone' - but do make absolutely sure you know yours before you try this tip...!
