Theres instructions on how to install it here https://techcommunity.microsoft.com/t5/Windows-Kernel-Internals/Windows-Sandbox/ba-p/301849 Wonder how it compares to oracle virtualbox, right now my win 10 sandbox is 32gb. Oh this sounds vastly preferable

The majority of the files are links (immutable files) and that's why the small size (~100MB) for a full operating system. We call this instance the “base image” for Windows Sandbox, using Windows Container parlance. When Windows Sandbox is not installed, we keep the dynamic base image in a compressed package which is only 25MB. When installed the dynamic base package it occupies about 100MB disk space.

As to how secure it is, i'm sure we'll find out, but it seems like a decent alternative for end users. Not something that any enterprise would want to jump at though.

@scatman839 "As to how secure it is, i'm sure we'll find out, but it seems like a decent alternative for end users. Not something that any enterprise would want to jump at though." I think it can be made decent for Enterprise users with a couple of adjustments for domain usage.

Can you run windows in this sandbox? We never know if it's trying to delete our data or collect our data now anyways.

to have a sandbox software is a must for me, but i think third parties have figured it out better, i use a software called sandboxie, and it is not a virtual machine (basically windows sandbox is a VM) it isolate the running software on a separate instance. very useful. is cool to see Microsoft doing this kind of things but i would like a better solution than a VM.

One doesn't replace the other. Sandboxes are great until you figure out how to escape them. Sandboxes are basically containers segmented off from the rest of your operating system. Virtualization is an environment that simulates an entirely separate computer. They both have their purposes and it isn't uncommon to see someone running a sandbox in a virtual machine but asking if this new offering from Microsoft is better than going with something like VirtualBox doesn't make a lot of sense to me. Just sayin'.

Still not a valid solution for high performance software, otherwise it would be available in all version of Windows because it could be used as a near zero overhead DRM in combo with a simple signature. At least gpu memory manager is able to access the virtual address space with WDDM 2.5, which is better then nothing.

Very interesting. But id rather use a VM until this sandbox thing matures if it ever does.
