Hello,
First of all, it would be fine to salute before beginning to ask your question.
Microsoft Office 2008 is not for Windows but for MAC computer. If you want Microsoft Office you have to purchase it, it's not free.
But you can download and try OpenOffice.org Suite which is free, and compatible with all other major office suites.
Best regards
