Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 86. This policy is obsolete because dedicated web platform policies are now used to manage individual web platform feature deprecations. Specify a list of deprecated web platform features to temporarily re-enable. This policy lets you re-enable deprecated web platform features for a limited time. Features are identified by a string tag. If you don't configure this policy, if the list is empty, or if a feature doesn't match one of the supported string tags, all deprecated web platform features remain disabled. While the policy itself is supported on the above platforms, the feature it's enabling might not be available on all of those platforms. Not all deprecated Web Platform features can be re-enabled. Only the following explicitly listed features can be re-enabled, and only for a limited period of time, which differs per feature. You can review the intent behind the Web Platform feature changes at https://bit.ly/blinkintents. The general format of the string tag is [DeprecatedFeatureName]_EffectiveUntil[yyyymmdd]. Policy options mapping: * ExampleDeprecatedFeature (ExampleDeprecatedFeature_EffectiveUntil20080902) = Enable ExampleDeprecatedFeature API through 2008/09/02 Use the preceding information when configuring this policy. Example value: ExampleDeprecatedFeature_EffectiveUntil20080902

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.
