Enable Windows Sandbox in VirtualBox
To enable and use Windows Sandbox in VirtualBox virtual machine, follow these steps- There is a specific setting that you need to enable in order to use nested virtualization in VirtualBox virtual machine. This is called Nested VT-x/AMD-V. Although it says VT-x, you cannot allow this feature if you have Intel CPU. To find this setting, open the VirtualBox, select the virtual machine, and click the Settings button. After that, switch to System section and go to the Processor tab. From here, you need to make two changes. First, you need to assign at least 4 cores to the virtual machine. You can use the Processor(s) bar to raise the core number. Secondly, you need to select the Enable Nested VT-x/AMD-V checkbox.
After that, click the OK button to save your change. Now, start your virtual machine, and search for Turn Windows features on or off in the Taskbar search box. After opening the Windows Features panel, you should be able to enable Windows Sandbox as usual. Hope this tip will be helpful for you.
