I wanted to get rid of some of the extensions and instead of doing that DOpus-only decided to block them system-wide, but then realized that none of the usually recommended tools in guides like Shell extensions which are blocked by default and other places worked (shexview, shmnview, EcMenu)
Then I saw that in DOpus these are UWP extensions, and my guess is those tools are ancient and simply don't support the new ones.
I've found a manual workaround of adding CLSIDs to the registry block list (DOpus is helpful in providing those IDs), but I'm curious if anyone knows of any tool that can list all shell extensions, including UWP ones, and block them system-wide?
