Yes, if you look here System requirements for Microsoft Defender Application Guard - Windows security Windows 11 is mentioned without (pro, edu or enterprise).
And under install description for stand-alone:
Applies to:
Windows 10 Enterprise edition, version 1709 or higher
Windows 10 Pro...
Windows Defender Application Guard (WDAG) is supposed to run on Windows 11 Home (not like Windows 10). But I can't find it in Windows Features and the Powershell way does not work either. Any ideas?
