Rebooting between Windows and Hyper-V causes OS to need activation again

[Andrew Brehm]

Whenever I reboot between Windows with and without Hyper-V (I use VirtualBox for some tasks, Hyper-V for others) Windows 10 imagines that it needs activation.

When I try to activate, a red message tells me that it could not activate (I don't know why it was trying) but the troubleshoot button activates it immediately without further problems.

Any ideas what might cause this and how to fix it?

When you reboot is it booting in to a VM with another Windows installed? If yes, then perhaps Windows thinks the hardware has changed, which is true, prompting the need to reactivate.

No, it's just rebooting with "hypervisorlaunchtype Off". I never got booting into a vhd to work. And if I did, I would use another key in that vhd.

Chances are you've probably done this already.
