    PortableBaseLayer is definitely the Sandbox.

    what I am curious about is, how do we free up the reserved space from a clean OS install. Without doing something like inplace upgrade. The registry tweak won't do anything, unless you upgrade.

    It showed up for me after using the sandbox as well. But it never went away when I closed out my sandbox either. Or like the OP mentioned it could be that it is reservedspace, and since optional features such as sandbox are installed to reservedspace, this is why it's there. So other optional features may trigger its appearance as well.

    It doesn't go away unless you disable the Sandbox from Windows Features or some other way. If you do, it's gone. Unsure about Sandbox using Reserved Space, at least it would make the feature depend on Reserved Space being present.

    Oh, for those interested in performance, having Sandbox, HyperV, or VBS (Virtualization Based Security) enabled, pretty much anything that requires virtualization, will have a pretty big impact on performance, around 5-20% measured through all the AIDA64 test suite. I just got rid of mine, and enabling/disabling HyperV as needed. VMware didn't seem to have this issue, which is quite annoying.

    Unfortunately, In-Place is the only current remedy for that (zapping the Portable Base Layer virtual drive). Least all I have ever found. Hopefully, MS will come up with a "Clink here and reboot, and all go bye-bye".

    Reserved space deals with MS's effort to help you have enough space for updates, upgrades, that sort of thing. No connection with Sandbox. Really only pertinent for 32GB and smaller tablets. I zapped that with the reg tweak and rebooted....all gone, doesn't show any more under Settings>Storage.

    Are you talking about when it's actually in use, or all the time? Doesn't make sense that Sandbox would use up all those resources when it's completely closed.

    Pretty much all the time; simply enabling it would result in a hit in almost all the AIDA64 tests. CPU-Z bench however had the opposite result, the bench ran a bit better with Hyper-V enabled. No need to have a VM running, or even access HyperV, all it takes is enabling the feature (or any other feature that makes use of HyperV) and rebooting as necessary, and if you perform a before/after series of benchmarks you'll be able to see the hit for yourself.

    Won't notice it in day to day use, or gaming (at least not o my PC), it's mostly a benchmark thing.

    What components are affected. CPU, RAM, HDD speed? I assume CPU is hit the worst?

    When Sandbox is opened, the virtual drive is "attached" as it's home to play in. When Sandbox is closed, the virtual drive is "detached", off-line per se. It's just there, sitting, doing nothing. Not a whole lot different than mounting an image, doing what you want to, and dismounting it. I can't see how an idle detached vhdx can have an impact on anything.

    I didn't test the disk performance at all. I'm attaching the AIDA64 benchmarks, they're in html format and easy to compare.

    It's not the vhdx, it's the hypervisor being active. You can check it in msinfo, once you activate Sandbox, even if you don't use it, it will enable VBS. The pic below is without it enabled, just to show where you can find it.
