Recently (the past month or so), my Windows VMs are hanging on boot occasionally (once per week or so). They just get to a "locked" state. Clicking "Actions | Reset" and reverting to a snapshot just hangs as well - necessitating me to reboot my machine. After updating to the latest PD15 this morning (15.1.2), I was hopeful it would help - but now I'm getting the same behavior every time I'm try booting the VMs. This is on a couple of different Windows 10 VMs and with a Windows 7 32-bit VM. I am not having any issues with any of my macOS or Linux VMs.
