Minecraft creator Markus "Notch" Persson has refused to allow Microsoft to certify the game for Windows 8's app store.
Minecraft creator Markus "Notch" Persson recently refused to send his game through Microsoft's certification process for approval to the Windows 8 app store. Persson was quoted via twitter, telling Microsoft that he'd "rather have minecraft not run on win 8 at all than to play along." and told Microsoft that they should "stop trying to ruin the pc as an open platform."

If Minecraft does not achieve it's Microsoft certification, it won't appear in Windows 8's Modern UI (formerly Metro) software catalog. This will make it a bit of a clutter to play, but should still be usable; if perhaps only through the desktop environment.
Windows 8's "Modern UI"
Persson has been a long time opponent of Windows 8, and his main concern is that Microsoft is making it more constrained, making it less open and friendly to developers. At this time, the Windows app store is optional for developers, but a future in which it becomes mandatory isn't hard to imagine, and that would give Microsoft unprecedented control over the software being published for Windows. Markus Persson is not alone either; Gabe Newell, CEO of legendary developer Valve, has been quoted saying that Windows 8 "could be a catastrophe" for pc gaming.
Microsoft's intentions with the certification process is to create a software catalog that functions properly in Windows 8, and provides security and value for users. The certification process will also involve content regulation and ensure that the software meets Microsoft's requirements by not providing offensive content.
