Microsoft Signature Edition PC
Introduced last year, a Microsoft Signature PC is configured by Microsoft engineers to operate at peak performance with superior reliability. It includes 30 days of free technical support for your software. Buy a new PC and you can get free phone support for the first 90 days. These PCs include the following Signature suite of programs:
Internet ExplorerWindows Media CenterInternet TV Update for Media CenterPlay-ready PC Runtime for WMCMicrosoft Security EssentialsMicrosoft SilverlightAdobe Flash Player for IEAdobe Acrobat ReaderBing 3D MapsZune 4.0Windows Live Essentials.
If you have purchased your PC elsewhere but want the Signature experience, you can still go in for the Microsoft Signature Upgrade. If your PC already runs Windows 7, you are good to go and you do not need to pay anything more! However if you are upgrading from Windows Vista or Windows XP, you will have to purchase a Windows 7 Upgrade license.
