First of all it's Microsoft Office not windows Office. Secondly you can load Microsoft Office from version XP upwards on most PC's or laptops if you have the serial number. Unless licensed to do so you can only load onto one PC or laptop. Once you have loaded it you have the option of activating it online or by phone. If you pick the phone option you will be asked to enter the serial number and then you will be given an activation code to either write down and enter afterwards or enter it as you go.|||Yes, you can call MS for the activation code.
