Windows Sandbox

Hello, I just recently joined Windows Insider. I did this because I heard about Windows Sandbox as I am afraid of viruses. When I updated to Windows 18305.1003, I didn't receive Windows Sandbox. I have everything required including the Virtualization setting turned on. Is there an option to manually install? I would love the option to test viruses. (Yes I have Windows 10 pro).

Fist  you have to uninstall Cumulative Update 18305.1003 (KB4483214). Sandbox doesn't work when this update is installed.

To prevent installing this CU download and run wushowhide.diagcab  which will hide that update.

Now you can follow these instructions to set Sandbox.
