'Iffy' copies of XP.
Not that anyone here would have, but IF they knew anyone who had, it would be a good idea to ensure that the latest update is not allowed to install on their PC.
IF anyone had, and has not yet restarted their PC, go to system restore and go back to yesterday, then into control panel updates, and disable auto update. Once the machine has been allowed to restart after the install I am led to believe that otherwise a niggle screen pops up and starts to become a PITA.
