18920	KB4512941 causes VirtualBox to crash VM with illegal instruction	CKing123		"After installing KB4512941 (this is repeatable by uninstalling it when VirtualBox (version 6.0.10 and the newest version 6.0.12 I haven't tested any other versions) works but installing it again causes the bug). This is the case with two Windows guests (one being Windows 7 guest (BIOS only) with the other being Windows 10 guest (turned on EFI for special guest OS setting in VirtualBox))

I reported this issue to both Microsoft and I am reporting it here since I don't know whether this is a Virtualbox bug or Windows bug. For now, I rolled back the KB update."	defect	closed	other	VirtualBox 6.0.12	obsolete			Windows	Windows
