Cannot use Close (X) or move a Window
Deputy head has dumped there home PC on my desk, and its got a problem i have not seen before. You cannot use the buttons in the top right of a Window, ie the Close X button or the minimize, and you cannot drag the Windows anywhere else on screen, pressing Alt + F4 works. I have run Malwarebytes and it says nothing found, and an SFC /SCANNOW and thats not fixed it. Anybody come accross this before? Google seems to come back with nothing that relates to this issue.
