I hope I can explain this clearly. When I open a file (.mp3 in my case) that opens with the preferred program (VLC in my case), the program is not focused (greyed out, first screenshot) until I click on the window then it becomes focused (not greyed out, second screenshot). I want it to be focused without having to click on the program window upon initial opening. This will make my batch work much faster and less painful if I don't have to click every single time I open a file.
chkdsk
, do SFC & DISM, and if nothing do Repair Install of Windows 10 with an In-place Upgrade.
