Ok so I tried adding the Edge admin templates and it made no difference. I decided to spend (waste) my time finding this and after much trial and error, I found that it is in fact this: Computer > Policy > Admin > Windows Components > Windows Defender Smartscreen > Explorer > Configure Windows defender Smartscreen Turning this on, enables this setting. I will note that I had to install May and October 2020 admin templates in. May 2020 https://www.microsoft.com/en-us/download/101445 October 2020 https://www.microsoft.com/en-us/download/details.aspx?id=102157 You may have to restart the PC for this to apply - GPUPDATE /FORCE does not apply it ![43716-screenshot-2020-11-30-170204.jpg][1] [1]: /api/attachments/43716-screenshot-2020-11-30-170204.jpg?platform=QnA

I turned on that one option and if you flick it off/on it will stay on and grey out to not be configurable. Or, a restart would have forced it on.

2021-11-01T20:25:34.52+00:00 I had a similar problem for Windows Server 2022
I had the following GPOs set:
Windows Components/Microsoft Defender Antivirus- Configure detection for potentially unwanted applications: Enabled = Block
This is how it appears in Windows Server 2019
And this is how it appears in Windows Server 2022
There is a new setting introduced with Windows Server 2022 for "Block downloads".
The GPO setting to control that is:
Windows Components/Microsoft Edge/SmartScreen settings- Configure Microsoft Defender SmartScreen to block potentially unwanted apps: Enabled
App & browser control will then show as fully turned on.
In summary, the PUA GPO settings are as follows:
For Windows Server 2016:
MS Security Guide- Turn on Windows Defender protection against Potentially Unwanted Applications
For Windows Server 2019:
Windows Components/Microsoft Defender Antivirus- Configure detection for potentially unwanted applications: Enabled = Block
For Windows Server 2022
Windows Components/Microsoft Edge/SmartScreen settings- Configure Microsoft Defender SmartScreen to block potentially unwanted apps: Enabled
