Desperation is setting in at MS it seems http://www.theregister.co.uk/2016/05/06/microsoft_update_asus_windows_7/
A recent Windows 7 update partially bricks computers that have an Asus motherboard fitted, it emerged this week.
Windows 7 machines that have installed Microsoft's KB3133977 update may trigger a "secure boot violation" during startup, preventing the PC from loading the operating system, Asus said.
Though the KB3133977 patch has been out for a while, Microsoft has only this week changed its classification from "optional" to "recommended", meaning for many users it now automatically installs through Windows Update – and then borks the PC.
The problem, Asus says, is that its newer boards support Unified Extensible Firmware Interface (UEFI)'s Secure Boot mechanism by default to prevent firmware and operating system tampering. Windows 7, however, does not support that feature, so it's normally not used.
I'm surprised they havent "leaked" some of the older unsupported O/S sources yet to help attackers drive folks onto their latest spyware ridden offering, maybe thats next
