Hello, I have the following version of Windows:

Enabled Sandbox in system components, but when I try to open it via Win+R, the following error appears: “Cannot find ‘windowssandbox’. Check if the name is correct and try again.” What to do?

Hello

Thank you for posting in Q&A forum.

Please check the Prerequisites in the link below.

Arm64 (for Windows 11, version 22H2 and later) or AMD64 architecture
Virtualization capabilities enabled in BIOS
At least 4 GB of RAM (8 GB recommended)
At least 1 GB of free disk space (SSD recommended)
At least two CPU cores (four cores with hyper-threading recommended)

If the Prerequisites is met, you can try to install Windows Sandbox based on the steps below.

Ensure that your machine is using Windows 11 or Windows 10, version 1903 or later.
Enable virtualization on the machine.
- If you're using a physical machine, make sure virtualization capabilities are enabled in the BIOS.
- If you're using a virtual machine, you need to enable nested virtualization.
Use the search bar on the task bar and type Turn Windows Features on or off to access the Windows Optional Features tool. Select Windows Sandbox and then OK. Restart the computer if you're prompted. If the Windows Sandbox option is unavailable, your computer doesn't meet the requirements to run Windows Sandbox.

Greetings. Thanks for answering my question first!

I did everything according to your instructions, after enabling in device components, my laptop rebooted, started applying updates, asked me not to turn off the computer. Then, a few minutes pass, I see something goes wrong, it reboots again, rolls the update back, says something went wrong and canceled the last update, laptop reboots. Sandboxing, alas, still doesn't work. I don't know what the problem could be. Help, please.

Since it’s a preview build, if you encounter issues with Sandbox or other features, also remember to provide feedback through the Windows Insider channels can help Microsoft improve the final version.
