Enable or Disable Reserved Storage in Windows 10

It also looks like 2004 upgrade remembers when drives were last optimised - which is good.

Try a Restart, or sign out and back in. Mine says 'never run' after that.

Yep - I guess this is deliberate, like the hidden MSR partition. It was always annoying seeing it.

Also, in past, disabling sandbox used to make it disappear which gave illusion it was linked to sandbox somehow. Presence or not of Sandbox no longer affects visibility of portablebaselayer.

EDIT 1: just double-checked - removing Sandbox remove the drive from Minitool as well.

EDIT 2:

just double-double-checked - adding Sandbox brings back the the drive in Minitool as well.

I kind of wonder if portablebaselayer is actually for sandbox and the 8GB Reserved Storage is another superhidden "drive"?

What a FusterCluck!

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.

Read these 2019 posts.

The portablebaselayer thing has NOTHING to do with reserve storage. Everything to do with the Sandbox feature.
Which you shouldn't use if you care about extracting max performance from the PC, because it means the HyperV hypervisor is enabled and active at all times, which comes with a performance hit (there are benchmarks too in my earlier posts).
For testing potentially unsafe apps or websites, use VMware player or something. No performance hit.

Will reboot now.

Yup, says never run

First, I have tested my laptop with and without hypervisor running, and I could not detect any performance hit.

More importantly, I use Hyper-V all the time and it far out performs VMware.

Your advice is based on your limited experience, and you cannot generalise to all users.

Yes it's 2004 and both show as using 8 gig.

The odd thing is mine did too initially but when I removed sandbox , the portablebaselayer disappeared, and when I reenabled sandbox, it remained hidden.

Try it.

I tested with Aida64 and cinebench on two PCs with different architectures. Is not about the VM performance, but about the host, which is affected if hyperV is enabled, no need for VMs to be running. Some bench should still be attached to an earlier post here, because I like to provide data, if I can. hyperV is great, but it has some disadvantages for the host. If all you care is the sandbox, I'd argue that VMware player is a better solution, no weird partitions, no host performance impact.

Computers that have been upgraded to 1903 then 1909 then 2004 do not yet have reserved storage.

Microsoft made reserved storage available to computers that were preinstalled or clean installed 1903 and later upgraded or preinstalled or clean installed 1909 and later upgraded.

The commands to get reserved storage information may display error 87.

Reserved storage will be introduced automatically on devices that come with version 1903 pre-installed or those where 1903 was clean installed. You don’t need to set anything up—this process will automatically run in the background. The rest of this blog post will share additional details on how reserved storage can help optimize your device.

How to Disable “Reserved Storage” on Windows 10

What is Reserved Storage on Windows 10 1903?

This link has recent changes:

Microsoft Adding Options for Controlling Reserved Storage in Windows 10 -- Redmondmag.com

With the coming updated DISM tools???

Originally, the Reserved Storage feature was depicted as only being available on new PCs running Windows 10 version 1903, or existing PCs that had Windows 10 version 1903 (or greater) "clean installed." Machines running older Windows 10 versions didn't have the Reserved Storage feature, and weren't going to get it. With the coming updated DISM tools, it'll now be possible to switch machines running older versions of Windows 10 to use Reserved Storage, if that's wanted. Once switched, these machines continue to use Reserved Storage upon subsequent OS upgrades.
