Information
This setting lets you decide whether employees can run Adobe Flash in Microsoft Edge.
The recommended state for this setting is: Disabled.
Rationale:
Adobe Flash is a very insecure product and has been a frequent attack vector on the web. In more highly security-sensitive environments, Adobe Flash should be disabled completely to eliminate this attack vector.
Note: This setting will not prevent or remove Adobe Flash usage from other web browsers, so we recommend also uninstalling Adobe Flash completely from all systems in highly security-sensitive environments.
Impact:
Users will not be able to use Adobe Flash in Microsoft Edge.
Solution
To establish the recommended configuration via GP, set the following UI path to Disabled:
Computer Configuration\Policies\Administrative Templates\Windows Components\Microsoft Edge\Allow Adobe Flash
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MicrosoftEdge.admx/adml that is included with the Microsoft Windows 10 Release 1703 Administrative Templates (or newer).
Default Value:
Enabled. (Users will be able to use Adobe Flash in Microsoft Edge.)
