Disable internal Edge Adobe flash player

Flash is a big security hole, so we disable it now.

Go to
HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\Addons
and change the DWORD string
FlashPlayerEnabled
to
0


Finish. No restart required. You can config this in Edge settings too.
