Re: Forced to use Flash
My current solution is to restore from a backup image once a week or so to remove all traces of flash.
It comes with windows 8 and higher on IE, so removing all traces of flash can be time consuming if you are using windows OS (disregarding macOS and linux).
Instead of restoring from a backup once a week, you might be better off keeping a hard drive with flash and removing it when you don't want it to be used. Or install/ use flash in sandboxie/ VM, and delete the box as soon as you finished to save a lot of your time.
