16798,Black screen,peterk,,"I saved a snapshot Januari 1. It contained VirtualBox 5.1.12 and at that time, the current version of Windows 10. After a Windows update in April 13 the screen in Windows i just black. 

I have tried to update to VirtualBox 5.1.22 and 5.1.23 and running a new Windows update. Still a black screen after logging in to Windows.

If I revert to VirtualBox 5.1.12 and the snapshot from Januari, everything looks fine. After a Windows update the screen turns black.

The host is running OS X version 10.12.5",defect,closed,other,VirtualBox 5.1.22,worksforme,,,Windows,Mac OS X
