Basically, the functioning of the Windows Sandbox feature is supported by various components in the background of the Windows operating system.
Sometimes, Windows users experience their Sandbox item greyed out in the Turn Windows features on or off utility.
Here at Outsource Path, as part of our Technical Support Services, we regularly help our Customers to fix Windows related issues.
In this context, we shall look into steps to resolve such problem in your Windows 10 computer.
Windows Sandbox provides a lightweight desktop environment to safely run applications in isolation. Software installed inside the Windows Sandbox environment remains "sandboxed" and runs separately from the host machine.
A sandbox is temporary. When it's closed, all the software and files and the state are deleted.
In order to enable Windows Sandbox feature in your computer , you can implement it via 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.
This issue has something to do with the Second Level Address Translation which is one of the important pillars on how the Windows 10 Sandbox feature functions. Thus, if the Second Level Address Translation or SLAT feature in Windows Sandbox is not supported by the CPU of your computer, there is no way for you to use Windows Sandbox in your computer.
Similarly, if SLAT is supported, then there is definitely something you can do to resolve the greyed out Sandbox item in Windows 10.
To fix this issue, simply follow the steps provided below.
1. First, you have to boot into the BIOS of your PC.
2. After that, make sure that the following options are set to their respective configurations:
i. Hyper-V – Enabled
ii. VM Monitor Mode – Yes
iii. Virtualization – Enabled
iv. Second Level Address Translation (VT-d or RVI) – Enabled
v. Data Execution Prevention – Enabled
3. Once you’re done, save the configuration and then restart your Windows 10 computer as usual.
4. Once your computer has restarted, you should see the same option in the Turn Windows features on or off utility and it should no longer be greyed out.
Then you can now enable the feature and follow the onscreen instructions need to use the feature as best as you can.
