Only option I know is to use Hyper-V virtual machines. I run Sandbox in Windows 10 on a Hyper-V VM, and save a Standard Checkpoint of that VM when I want to save Sandbox state.

Restoring / applying that checkpoint, Sandbox is where I left it.

There is no way to save state of Sandbox when you close it.

Another way but a bit clunky is to make an incremental image backup just before closing it down (and an icremental image before you wind back. I have an amd processor and cannot run sandbox in a vm.

I wonder when Microsoft will fix this. Nothing wrong with the hardware, just lacking MS support, which is ridiculous.

I see! Thanks for this information.

No solution yet that we know of. We're waiting to see if the solution provided by Microsoft in late June will also sort it.
