The shop that repairs my PCs lost my genuine Windows 7 OS somehow. So they have burnt a copy of Win 7 onto a blank and claim if I ever reinstall Win 7 I can still use the serial numbers on the case of this PC they sold me a year ago. I thought every Win OS disc has the its own serial number encrypted. But it seems are all Windows OS disks the same for each OS, and it is really just the serial numbers that are unique and checked by MS online as genuine.
Is it still possible to connect a nice big monitor and speakers to all modern laptops and Tablets even though some are so thin now they may not accommodate a VGA Socket?
