Proper removal of Discord App (Windows)

After having trouble with the PTB-Version, I got quick replies from the support team (thank you for that, everything worked out good), but even their "tutorials" for uninstalling and reinstalling Discord required the manual removal of Folders in the %appdata% and %localappdata% folders. For a modern program, used by lots of "nerds", this should be a no-go.
The standard uninstallation should properly remove all traces of the program from the pc, as a customer would expect when clicking on "uninstall" (or "remove"? Not sure how it's called in English...).

Also, the uninstallation via the programs and features-tool of Windows just removes Discord from the list without any feedback - leaving the user to wonder, if really anything happend (and after the above mentioned problems, I somehow doubt it).

Would be nice to fix this, even if it might not be relevant too often ;)
