I've just tried to install GeoServer on Windows 10 and I'm greeted with a red
notification stating that SmartScreen has prevented its installation, and that the
application might be dangerous:
https://osgeo-org.atlassian.net/browse/GEOS-7808
It does not matter if the application is run as admin or not, the message remains the same.
I've searched a bit on the internet, was the application signed by any chance? Signing the app without
fully following the expected auth procedure seems to cause installation blocking:

Hmm... this sounds like a blocker to me...
