I probably can't help, as I don't know anything about Docker. I was just curious why it is important to use the same OS in your VHD as on your laptop.
If you think 'goto' is evil, try writing an Assembly program without JMP.

Years ago I used Altiris SVS. It was free and Symantec bought it IIRC. I used it for years after they quit making updates to it.
A quick search because I couldn't recall the name, led me to this: Cameyo[^]. At the bottom of the page, they have something called Cameyo Offline. That sounds like what you might be looking for.
I'm going to play with it and see what it is like.

Wow, you nailed it. Symantec Workspace Virtualization is exactly what I was looking for (too bad it's discontinued lol)
Symantec Workspace Virtualization - Wikipedia[^]
Quote: Originally pioneered by Altiris and based on technology acquired from FSLogic and named Software Virtualization Solution, SWV allows applications and data to be put into virtual layers (application layers and data layers) instead of being installed to the base file system and Registry. This is achieved through the use of a filter driver and layering technology Altiris acquired from FSLogic. By placing applications and data into managed layers called Virtual Software Packages (VSP's), SWV allows on-the-fly activation, deactivation, or reseting of applications, to avoid conflicts between applications, and to remove them cleanly without altering the base Windows installation.
I'll have to check out Cameyo!

What you just described is a VM using snapshots. Docker uses VMs under the hood, but it's an app container within an isolated environment. The keyword being app here. If you want a root OS type thing going on, you're looking at a VM directly.

Just to avoid confusion... Docker For Windows[^]. However, it's for contained apps on Windows and not the root OS itself.

Apparently it is possible to containerise at the OS level (linux anyway - LXC's).
Depends how you use your machine, for me my base (w7) machine is tuned for dev (i.e. many services turned off/manaul) so using docker at OS level wouldn't be a valid testing setup (even if I turned things back on in the container); for devs targeting individual desktops or/and servers it'll remain better to use a "clean/standard setup" VMs ("un-tuned" or tuned-like-the-customers-machines apart from perhaps a few other installed programs such as vs (or some debugger), and say ff and np++..)

My understanding of it, the way Docker works on Linux doesn't use a VM. The OS provides the functionality to contain processes, which is what is being linked to. And so Docker takes advantage of that. On Windows I didn't think there was a way to do that without a VM. But, I'm a total Docker n00b, so who knows.

So when you mean at the OS level, are you not using Hypver-V or any VM at all, or is it going through Hyper-V still but you're just turning off/on Windows features, etc.?

In this I meant my own machine has everything turned off I can get away with,
so to do effective testing I would need a proper VM (i.e. installed "normal" setup) rather than a docker container which relies on the underlying OS.
Some good summaries here: stackoverflow.com/questions/16047306/how-is-docker-different-from-a-normal-virtual-machine
(on purpose pasted as text rather than a link, in case you don't like links.)
About 1/4 ways down a good mention of the LXC'c...
Quote: Linux Containers (LXC) are operating system-level capabilities that make it possible to run multiple isolated Linux containers, on one control host (the LXC host). Linux Containers serve as a lightweight alternative to VMs as they don’t require the hypervisors viz. Virtualbox, KVM, Xen, etc.

Look at Turbo Containers - Run Applications Anywhere (Previously known as Spoon)
And stay away from Docker for Windows. I'm using Docker Toolbox with .NET Core 2 and quite happy with the process. I wrote about my Docker for Windows experience here and here.

Thing is, I have Docker set up on a couple of QA Ubuntu servers, acting as replicas of prod environments, and they are brilliant. It makes testing so much easier because the image acts as a clone of prod, so I have a faithful reproduction that I can test against.

Just read the first part of the first link, and I believe you just confirmed what I think. Docker for Windows requires Hyper-V correct?

Its isn't a turnkey solution, but what you describe is essentially what Microsoft's Desktop App Converter[^] does -- it virtualizes the file system, registry, etc. for the desktop app that's being converted, and creates an installable windows UWP package. It probably won't keep that installed app from mucking with the main file system and registry once the installation is running on your machine, but at least all the registry keys and files related to the app itself are in a container.
I keep waiting for MS to deliver the community version of Visual Studio that way, so I don't have to permanently suffer the 750,000 registry entries it creates during installation on my personal machine, just to have it around for the odd time I want to use it.
Or.. would a sandbox product work? Something like SandboxIE maybe?
