I just had my first experience with Windows 10 and with Defender. I read and followed the suggestions in the Defender Thread, but I did find it somewhat long and confusing, which is not surprising how it evolved as people understood more about how Defender works, in particular how exclusions work. From my reading of the thread, it seems that the folder exceptions work fine and with them there may only be 2 exclusions needed - the Program Files\JRiver folder (or Program Files (x86)\JRiver) and the %appdata%JRiver (Users\USERNAME\AppData\Roaming\JRiver) folders. And neither of them refer to a specific version of MC. If there is agreement on that, then perhaps there should be a new sticky with that recommendation or maybe a modified initial post in the original thread with that recommendation. A single post with instructions as to how to get to the exclusion section of Defender like Awesome Donkey posted originally, and then these 2 simple exclusions would make it a lot easier for people, especially when JRiver changes to a new version. People could still refer to the whole thread for more details, but I think most people will be satisfied with just those 2 exclusions, and never have to worry about it again.
In fact, AD's original post did a great job of recommending excluding those 2 folders and the main MC executables. So, it has pretty much what I am suggesting already, except it includes the MC executable, which should be unnecessary and is version dependent. It then says that should be enough but then goes on to list all sorts of individual exclusions. So, a small tweak to that section to exclude the executable, with a stronger statement about not needing to do individual exclusions may be all that is needed. And a statement that this is the current update would make people more comfortable about not having the read all the rest of the detail.
Anyway, those are my thoughts after going through this process.
What say ye - AD?
