VirtualBox 6 使用WDDM Driver
解決方式之一：RDP取消使用WDDM
I run a VM on virtualbox 6.1.26 r145957, and got an error,
2e90.3314: Error opening VBoxDrvStub: STATUS_OBJECT_NAME_NOT_FOUND
2e90.3314: supR3HardenedWinReadErrorInfoDevice: NtCreateFile -> 0xc0000034
2e90.3314: Error -101 in supR3HardenedWinReSpawn! (enmWhat=3)
2e90.3314: NtCreateFile(\Device\VBoxDrvStub) failed: 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUND (0 retries)
Driver is probably stuck stopping/starting. Try 'sc.exe query vboxdrv' to get more information about its state. Rebooting may actually help.
