Metro and Bloatware
To get onto your computer, most Metro apps have to be approved by Microsoft and then distributed through the Windows Store, similar to how you download apps for your iPhone, Android or Windows Phone device. But it's not clear whether the Windows Store would curb or prohibit device makers from installing Metro-style bloatware before their PCs ship.
Metro and Peripherals
Even if Metro-style bloatware rears its ugly head, Microsoft is trying to keep peripherals from filling up your machine with unneeded junk. Microsoft is pushing makers of webcams, printers, cameras, and other devices to focus on supporting the Metro side of Windows 8 instead of the traditional desktop.
In Microsoft's ideal scenario, you would connect your new Canon all-in-one printer to your PC and then Windows 8 would automatically download Canon's supporting app from the Windows Store. Microsoft in September said it would limit hardware makers to offering just one Metro app per external device.
Of course, in an ideal world most of your peripherals wouldn't bother with supporting apps at all. Do you really need that snazzy interface from Iomega to use your external hard drive? I didn't think so. The good news is deleting a Metro-style app will be a fairly easy process, so if you don't want an HP specially-designed printer interface, you can nuke it pretty quickly.
