PDF X-Change Editor update switches defaiult PDF handler

[frustrated]

Every time Patch MY PC runs its scheduled weekly check and updates PDF-XChange Editor I discover that the default PDF app has been changed from the SumtraPDF to PDF-XChange Editor. I first thought it was PDF-XChange but its author assures me it is not their app that is doing the change. This only happens when PatchMYPC runs a check and finds that there is an update to the app and installs it. Using Windows10 Pro 22H2 here and PatchMY PC is 4.5.0.4

This happens because running the installer of PDF-XChange Editor silently auto sets it as the default PDF app! There is nothing we can do about it, they need to change this behavior with their installer when runs silently.
And to be honest, whoever installs PDF-XChange Editor will actually want it to be the default app for the PDFs!
