How to turn ON Windows Defender in Windows 11 Sandbox

I'm using Windows 11 Pro and I'm already activated Sandbox, but in this "virtual box" i can't turn on Windows Defender (that works perfectly fine in my system).

My question is: how to enable Windows Defender in Sandbox?

 

How to turn ON Windows Defender in Windows 11 Sandbox

Sure, please. By the way, I've reinstalled (clean install) my Windows 11. Now I have Build 23545.ni_prerelease.230908-1421

Yet still there is no Windows Defender in Sandbox. I need it to test files on viruses.

 

No internet connection on Windows Sandbox

Hello bvonr,

Thank you for writing to Microsoft Community Forums.

Ideally, if your computer is connected to the internet, even the Sandbox has to be connected. There is no extra setting to turn on/off internet for Sandbox. Few issues regarding network connection on Virtual machines and Sandbox has been resolved
just by updating to the latest build. Kindly check with the steps listed below and see if it works.

Method 1: Disable Antivirus software.

I would suggest you to disable all the security software applications (e.g. Norton, McAfee) that are installed on your host (main) machine. It could be blocking the internet connection, so disable it and see if the issue persists.

Disclaimer: If you have Windows 10, you’ll get the latest antivirus protection with Windows Defender. When you start up Windows 10 for the first time, Windows Defender is on and actively helping to protect
your PC by scanning for malware (malicious software), viruses, and security threats. Windows Defender uses real-time protection to scan everything you download or run on your PC. Windows Update downloads updates for Windows Defender automatically to help keep
your PC safe and protect it from threats.

If the above suggestions doesn’t fix, kindly check with the method 2.

Method 2: Disable and enable the Sandbox feature from Control Panel.

Go to Control Panel >
Programs > Programs and Features > from the left top, select
Turn Windows features on or off > Scroll down to Sandbox, disable and enable it to check if it works.

Additionally, you may also refer to the suggestions provided in the article on
Windows Sandbox has NO Internet when the
host is connected to a VPN.

Please let us know the results. We are glad to help you further if the issue persists.
