Windows Store App Package Repository Registry Path

This article identifies the specific Windows Registry path responsible for managing Windows Store (AppX) application package repositories. It details the exact registry location used by the operating system to define where packaged applications are stored, explains the key values associated with repository management, and outlines the permission requirements for viewing or modifying these settings.

The Package Repository Registry Path

In the Windows Registry Editor (regedit), the path that controls the Windows Store application package repository locations and configurations is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\PackageRepository

Within this location, the primary string value that defines the default installation and staging directory for all Windows Store and MSIX/AppX packages is located under:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\PackageRepository\Root

By default, the Root value points to the hidden system folder: C:\Program Files\WindowsApps

Key Subkeys and Components

The Appx registry tree contains several subkeys that control package deployment and storage:

• **PackageRepository*: Defines the physical storage volume and path where modern applications are unpacked and stored.
• **PackageRepository*: Catalogs the package family names (PFNs) of installed applications, linking package identities to specific manifest and repository entries.
• **PackageRepository*: Contains individual metadata entries for each installed package version, including install paths and user assignment.

Permissions and Access

The PackageRepository registry keys and the corresponding WindowsApps folder are protected by Windows resource access controls.

• Default Ownership: The keys are owned by NT SERVICE\TrustedInstaller or SYSTEM.
• Read Access: Standard administrators can view these keys, but write operations are restricted to prevent corruption of the UWP/MSIX deployment pipeline.
• Modifications: Modifying these paths directly via the Registry Editor is not recommended for moving existing apps. Microsoft provides native storage management options in Windows Settings > System > Storage > Where new content is saved to redirect modern app installations safely to alternative drives.
