What to do if Windows Sandbox item is greyed out in Windows 10
As you know, the functioning of the Windows Sandbox feature is supported by various components in the background of the Windows operating system. And the only way for you to enable the Windows Sandbox feature in your computer is through the Turn Windows features on or off utility. This feature will work directly on the basis of Virtualization which is also supported by Hyper-V. However, there are some reports claiming that some computers have the Windows 10 Sandbox item greyed out in the Turn Windows features on or off utility. Thus, in this post, you will be guided on what you can do to resolve such problem in your Windows 10 computer.
