Watch out for this one folks..... the call comes from someone claiming to be from Windows' technical department. They ask you whether your computer is running slowly (how many people are going to say no to that?!!) and then, and this is the really bad bit, they ask you to go to your computer and start getting you to hit certain keys etc. We are not sure exactly what they are up to but it's definitely no good. They might be trying to access your computer remotely - definitely the most likely option - so whatever you do, DO NOT talk to these people or do anything on your computer that they ask you to.
