When I run Windows Sandbox, is Defender running?

I occasionally need a bit of shareware / free software. I’m always a bit paranoid about downloading those types of things, and usually check them out in Windows Sandbox (on Win 11 Pro). I don’t see any indication of Defender running though in the sandbox. I’m hoping when I download the file in the sandbox, defender will scan it. If Defender doesn’t bark and I like the program, I can then copy it out of the sandbox to my machine. When I go to “Settings” in the sandbox and search for Defender, nothing is found.
