Microsoft is reportedly selling PCs without the typical crapware found on proprietary Windows-based computers. Although the company resells systems from its hardware partners including Acer, Asus, Dell, Fujitsu, Gateway, HP, Lenovo, Samsung, Sony, and Toshiba, the standard third-party and in-house crapware is excluded. The machines aren't entirely clean though, as Microsoft bundles some software of its own.
Installed on "Microsoft Signature PCs" are the following applications: Microsoft Security Essentials, Bing 3D Maps, Zune 4.0, Playready PC Runtime (for WMC), Adobe Flash Player for IE, Adobe Acrobat Reader, Windows Live Sync, and Windows Live Essentials (which includes Windows Live versions of Messenger, Mail, Photo Gallery, Movie Maker, Writer, Family Safety, Toolbar, as well as the Office Live Add-In and Silverlight).
Granted, that's quite the list of software, but it's still an improvement over most systems straight from HP and others. Users would probably install a lot of the programs in one shape or another anyway, and Microsoft's packaged software could even prove helpful for the less experienced folks out there.
