This Windows 10 problem is known. In fact Microsoft want to promote
the Store in fact the direct download installer. They want to
reproduce the Apple model here. So the Windows defender drop
automatically the executable installed from outside the Store.

Publishing digiKAm to the store is possible, as another KDE
application already do it, This require:

1 a computer with Windows 10 to compile whole code and dependencies.
2 the Microsoft compiler
3 a compilation workflow to compile whole dependencies and finally the
target for the store (it's only possible with the Microsoft SDK)
4 an account to upload and validate the application on the store.

All these stages are more and less ready for digiKam using the
Continuous Deployment from KDE infrastructure, but the compilation
workflow is still broken with Microsoft Windows compiler. In opposite,
the Continuous Integration with Microsoft compiler work as expected,
so it mostly a settings problem with the compiler used with the
Continuous deployment (which is different than the Continuous

You must know that the whole digiKam Windows installer is cross
compiled under Linux with MXE. There is no Windows here. this prevent
virus and malware infection during this process.

Also using Linux is 1000 times more easy to program than Windows with
scripting. I hate to use Windows (and i must use it for development in
my office which is a waste of time).

Voilà for the technical details around Windows stuff and security
issue with Defender.

> While downloaded .tar.xz files are also marked as blocked, it is not necessary to unblock them. Windows itself cannot extract from .tar.xz .
