Hello Office girl,
If your Office Home and Student 2007 reports as Genuine here
www.microsoft.com/genuine when you click on the Validate Office button, then your clean installation of Office onto your clean installation of Windows should go very well.
After installation of Office, open Windows Updates and accept the offer of Microsoft Update, which will check for updates for Office as well. Office 2007 is up to Service Pack 2 plus many additonal security updates.
