Well, many things have changed since early 2017...
Hi Asyn, know what? Eventually I tried it myself, and found out that nothing has changed, at least about my issue (confirmed to be a possible scenario by an avast dev). Probably I am, if not the only one, one of the few who keep games in an external drive. At this point I don't think there will be "fixes", if I can say so. Component uninstalled.
No problem, there are other solutions. Long time ago I already created a "Game Mode" feature via vbs and bat files, which disables with one click unnecessary programs and background processes, changes desktop background and runs a launcher bar just for games. I was interested in that particular feature that focuses the CPU priority on games... something that can be done with Task Manager... but having it enabled without touching anything would have been good. This is not my case, because I need an external hard drive for old good and brand new games.
P.S.: And please, do not consider the "built-in" gamemode windows 10 pretends to "offer" to the gamer... It just doesn't work as expected with full screen games, and has conflicts with NVIDIA drivers... I already follow that route!
