The topic is Windows. Windows is not only a desktop OS anymore. The exact same code (since a few weeks even the same build numbers) is running Windows Phone and Windows tablets too. This is what is causing the issues that the OP is about: new hardware (both x86 and ARM) comes with new features in power management and virtualization (i.e. connected standby) which Windows needs to abstract and they find it too hard/risky to backport the OS and driver changes to every device now running Windows 7.
