The new program is an outgrowth of Microsoft's "Signature" PC initiative, which sells bloatware-free versions of PCs from Microsoft's partners in Microsoft stores. AllThingsD reports that Microsoft is now offering to change any computer into a Signature PC if customers bring it into the store and pay the requisite fee. Signature PCs also include Microsoft's Windows Live Essentials programs; the ad-supported, Word and Excel-only Microsoft Office Starter edition; the Microsoft Security Essentials antivirus package; and the Zune media player software. Users can choose not to have these programs installed, and can also specify if they would like other third-party browsers or programs installed. Ninety days of free phone support is also included.
