But to enable Windows Sandbox you need this in the Windows Features.
You look through the internet and surf away there are various suggestions. But what matters is the Windows Version you have. You would assume, that since you have agreed for automatic updates everything is fine. That is not the case.

I found out that I was running Windows 10 Pro version 1803 and that was the real problem. I tried to update to the needed version 1903 or higher but I was not able to do it from the desktop.

I had to get the Windows 10 Update Assistant to install the higher version.

I finally installed the Windows 10 Update Assistant and ran the program.

It takes a while and the installation would require you to have nothing connected to the USB Ports. If they are connected to anything you will get an error which is easy to correct.

Now with the new version you will see the Windows Sandbox in Windows Features as shown.

That concludes the task of bringing the Windows Sandbox node to the Windows Features.
