Enable the extended lifetime option for SharedWorkers
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 148, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
Controls whether Microsoft Edge allows SharedWorkers to use the extendedLifetime option. If you enable or don't configure this policy, SharedWorkers can use the extended lifetime option in the SharedWorker constructor. If you disable this policy, the extended lifetime option is ignored, even if it is requested by the page. This policy is temporary and will be removed in a future release.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: SharedWorkerExtendedLifetimeEnabled
Enabled: SharedWorkerExtendedLifetimeEnabled = 1
Disabled: SharedWorkerExtendedLifetimeEnabled = 0
Export Builder
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.
