Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Content settings User Configuration\Administrative Templates\Microsoft Edge\Content settings Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 87. This policy doesn't work because Flash is no longer supported by Microsoft Edge. Define a list of sites, based on URL patterns, that are blocked from running Adobe Flash. If you don't configure this policy, the global default value from the 'DefaultPluginsSetting' (Default Adobe Flash setting) policy (if set) or the user's personal configuration is used for all sites. For detailed information on valid url patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. However, starting in M85, patterns with '*' and '[*.]' wildcards in the host are no longer supported for this policy. Example value: https://www.contoso.com http://contoso.edu:8080

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
