Only one free trial period is allowed per computer. Microsoft would go broke if they gave away their software indefinitely. That's what happened to Sun Microsystems - they went belly up after giving away OpenOffice.
You can always purchase the full version of Microsoft Office, but if you don't need the full verison, Microsoft offers a free "light" version. The place you will find actual Microsoft Office (Word, Excel, PowerPoint and OneNote) for free in a "light" version is at the Microsoft SkyDrive site: http://www.skydrive.com If you have a Facebook account you can use Microsoft Office for free here: http://www.docs.com.
Just use Office Web Apps online, for free. When you sign into your Windows Live account, click on “Office” and you’ll be able to use the basic features of MS Word, Excel, PP and OneNote.
