I always keep everything up to date, but i use Ancile, which is a programm that turns off Windows Telemetry, it can be fought on Win 7 better then on Win 10, so i already thought that might be the thing that causes that window popping up, but i ran Ancile for many many months now and also used DS4windows and then InputMapper without any problems.
And as i said even, now the controller works just fine, it's just that if i want to change something in the settings or check the battery or something like that and click on the icon this message pops up, but the controller still works perfectly, thats why i said it's just a minor issue, an annoyance more then anything.
Look, 1.7 just doesn't work on my system. I just uninstalled 1.6.10 to try 1.7 again and no, doesn't work. Black window is all i get.
Here is a video. And btw, what i was showing also, but OBS somehow didn't record the overlay, was CPU usage, it was at 85% when 3 IM's were open(i didn't see them right away, but you will see that in the videos still.)
