I think we are talking about 2 different actions. You're talking about playinga torrent file. I'm talking about downloading the file to store it for future viewing. Let me explain again.
When I go to a website such as EZTV.io, and see a TV show that has been uploaded that I want to download and file, I go to the magnet link on that line, and left click on that link. Before I upgraded from WIN 7 to WIN 10, that left click resulted in opening the uTorrent app, and initiating the download process.
Now, with WIN 10, the left click results in a popup window that asks if I want to open uTorrent. When I opt to do so, the same process I described above begins, and all is well. I can continue to do this; but my point is that the popup window is an unnecessary step. The left click should automatically open uTorrrent, and begin the downloading. That popup window doesn't present any option for me to tell Windows to do this every time, without the popup. That is what I want to do.
