„MSI® HOW-TO install Win7 in B450 motherboard“
InfinityExpression: 14.7.2019: This is more than necessary, btw. great Bios-Update in only 3 Weeks MSI, Microsoft Windows 10 Version 10240 does not work with Ryzen Gen.1 and Ryzen Gen.2, the Motherboards are not the fault, the RAMs are not the fault. It is an exclusive incompatibility with Ryzen Gen.1 and Ryzen Gen.2 with a specific Windows 10 Version. Personally I think this is one of the biggest software scandals of all time (but also a critical hardware sandal bug of AMD and their idiotic idea to stop usb-2 support and deny people windows 7 experience by default, this is not acceptable in any way, considering the fact of the poor stability of windows 10 in combination with ryzen), considering that Microsoft misuses a monopoly position to produce defective Software, that has implemented the irrepairable Terror-Ghost-Design-Bug since Windows 8. Apart from that Windows 10 is a big failure because the Windows can´t be put on Top like in Windows 7 due to Tablet Mode, that basically screws every intuitive handling up, one could think they implemented this to Delay, Deny, Deteriorate, Degrade, Destroy (like GCHQs Terror-Motto) the complete Operation System experience since Windows 8. I can´t think of it as usual bug, it is such a blatant defect that one really has to think of it as intentional degradational sabotage act from Microsoft and its shadowry deterioration coder crew.
All have to go back to Windows 7, as a matter of fact…unbelievable scandal of this monopoly os-software giant.
