Control whether storage quota APIs will return static values
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 145, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
Controls how the Storage Quota APIs report the available quota to websites. When enabled, the Storage Quota APIs return a static quota value equal to the current usage plus the smaller of 10 GiB or the device's total storage rounded up to the nearest 1 GiB. When disabled, the Storage Quota APIs return a dynamic quota value that reflects the actual available device storage. When unset, the browser uses the default platform behavior. This policy does not affect sites with unlimited storage permissions or enforced quota settings.

Enabled: StaticStorageQuotaEnabled = 1
Disabled: StaticStorageQuotaEnabled = 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.
