Yes, W10 seems to forget some file associations, but I have found it easier just to fix them as an when they occur. No idea why it does this though.Tetenterre wrote:This new "big improvement" to W10 (aka Threshold 2) is a right pain: it changes many of your file associations from the application you were using to a functionally deficient Microsoft version.
Also, using the recommended method of changing file associations (Settings > System > Default Apps) limits the choice to stuff that someone has deemed appropriate for you. To choose your own, you need to do Control Panel > Programs > Default Programs > Associate a file type or protocol with a specific program, where you get an option to "Look for another App on this PC".
