@IDWMaster: Don't forget, anything written in WinRT MUST be installed from Microsoft Marketplace. Chew on that candy for a while! You no longer are ALLOWED to give YOUR application to whoever you like WITHOUT PERMISSION from Microsoft.
The bigger question is not about Win APIs, the question is, is your PC YOURS anymore?
Of course, anything else rather than praises and flowers will be bashed here by the 10-15 regulars hanging in here. Don't expect much from them. Their bags are all empty.
