Sorry if this may have been broached before. I attempted to read forum post prior to posting this question.
Host machine: Win10 Ver 1703 build 15063.483
Virtual Box 5.2.9
After Microsoft forced the update and rebooted my machine, my existing VM are unstable. Some I can get to boot but eventually will fail. I do not believe it to be guest specific but with VB Manager. If I attempt to start ANY existing guest and immediately try to access the options in the device menu, the guest becomes not responsive and will eventually give the error message below.
I rolled back as many of the updates as I could. There are two that will not. KB4049011 & KB 4025342. Performed Full system boot scan on host. Booting guests in safe mode experience same result. Any guidance will be greatly appreciated.
