Add another one to the list. Window Sandbox, the feature bundled with Windows 10 version 1903, allows users to run a separate virtualized environment in the OS to safely test apps and services.
It’s a virtual machine inside Windows 10, with a separate instance of the operating system that runs in a sandbox. This way, the system files are protected, with all the changes automatically reset once the application is closed.
The only problem?
Launching the app, what else?
Microsoft has acknowledged another little problem that affects Windows 10 version 1903 and up, including both the Pro and Enterprise flavors of the operating system. And this one actually affects both Windows Sandbox and the Windows Defender Application Guard (WDAG).
What happens is that when you try to run any of these two, you end up with an error that prevents you from using these applications.
This issue also affects the newly released Windows 10 version 2004, though it is not exclusive to it.
There is just one workaround available right now, and luckily, it’s not all that complex. All you need to do is reboot your computer, and the issue is mitigated. Obviously, not the most ideal of solutions, which is why Redmond is working on a fix.
No specifics on when this patch goes live, but it should be soon.
August 11, the date of the next Patch Tuesday is a solid bet.
