Manage Blob URL Partitioning During Fetching and Navigation
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 135, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Content settings User Configuration\Administrative Templates\Microsoft Edge\Content settings Description
The 'PartitionedBlobUrlUsage' (Manage Blob URL Partitioning During Fetching and Navigation) policy controls whether Blob URLs are partitioned during fetching and navigation. If this policy is set to Enabled or not set, Blob URLs are partitioned. If this policy is set to Disabled, Blob URLs can't be partitioned. This represents the Blob URL behavior before Microsoft Edge version 135. The policy is scheduled to be available through Microsoft Edge version 146. After this version, the policy will be removed, and Microsoft Edge will no longer support unpartitioned blob storage. For detailed information on third-party storage partitioning, see https://github.com/privacycg/storage-partitioning.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: PartitionedBlobUrlUsage
Enabled: PartitionedBlobUrlUsage = 1
Disabled: PartitionedBlobUrlUsage = 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.
