Two different releases of Microsoft Windows. Windows Vista Ultimate English 32/64 bit, from the Microsoft company store. This item is still sealed however please note the COA sticker has been taped to the back and was removed from the top, done presumably by the company store. Also included is Windows 7 Professional English 32/64 bit. This also came from the Microsoft company store. This box has been opened but DVDs inside look very nice. Please note the COA sticker details are hidden with an old Intel 8088 microchip which is not included!
