12445	None of my VM's work after upgrading to 4.3.4.91027	Master VB Guru		"After upgrading my Windows 7 Ultimate (64-bit) host machine to VirtualBox 4.3.4.91027, none of my VM's worked anymore.

Everytime I tried to launch them it told me a hardware setting was not correct.

I have since re-imaged my machine back to 4.2.18.88781 and now everything is working again."	defect	closed	virtual disk	VirtualBox 4.3.4	fixed			Windows	Windows
