I was trying to download an update for a game on my new Windows 10 System. The update is quite huge and just a few minutes before it was supposed to end, I had to leave my keyboard a few minutes. Then when I got back, there was a poup asking if I authorized the game to make changes to my system, I was about to click "yes"/"Authorize"/ but then the popup disappeared causing the whole procedure to be considered failed and now I have to re download the whole thing again (I don't blame the game developers, here).
How can I avoid this to ever happening again without turning off UAC?
