After adding the Hyper-V role, on the required reboot, the mouse (USB) and keyboard (PS/2) stop working and I can't get past the lock screen. The optical sensor in the mouse (USB) do not light up and the Num Lock and other lights do not light up on the keyboard, even when the keys are pressed.
I can access the system with remote desktop.
When I try to plug in a USB drive, on the Remote Desktop, it says "drive not initialized" even though it worked prior to adding the Hyper-V role.
SVM is turned on in the BIOS
The system works fine prior to this.
I have tried a full reboot, including turning off the the power switch for 20 seconds. Also, a full windows reinstall.
