Windows 10 Insider Preview Build 18305 Update Destroys Windows Sandbox

With Windows 10 Insider Preview Build 18305 (19H1), Microsoft introduced a new feature called Windows Sandbox, a lightweight desktop environment designed to run applications securely separately.

And recently, Microsoft released a new Cumulative Update for Windows 10 18305.1003 (KB4483214), but it turned out that this new update actually damaged the Windows Sandbox. You must delete this update to continue using the Windows Sandbox.

 

As asked by Pneuma Official on the Microsoft Answer Page "Hello, I just recently joined Windows Insider. I did this because I heard about Windows Sandbox as I'm afraid of viruses. When I updated to Windows 18305.1003, I didn't receive the Windows Sandbox. I have everything required includimg the Virtualization setting turned on. Is there an option to manually install? I would love the option to test viruses.

To solve this problem the user must delete the update (KB4483214) manually, so that the Windows Sandbox can be used normally as usual.
