System-Wide DLL Redirection Registry Key Location

Dynamic-link library (DLL) redirection allows administrators and developers to override standard Windows library search orders and force applications to load specific versions of dependent DLLs. This guide identifies the exact Windows Registry location required to configure system-wide DLL redirection and explains the necessary registry values to activate this behavior across all applications on a machine.

Registry Location

To configure system-wide dynamic-link library redirection, navigate to the following path in the Windows Registry Editor (regedit):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

Configuration Value

Within the Image File Execution Options key, the behavior is controlled by a single DWORD value:

• Value Name: DevOverrideEnable
• Data Type: REG_DWORD
• Value Data:
  • 1 — Enables system-wide DLL redirection.
  • 0 — Disables system-wide DLL redirection (default Windows behavior).

How to Apply the Setting

1. Press Win + R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options.
3. Right-click the Image File Execution Options folder, select New > DWORD (32-bit) Value, and name it DevOverrideEnable.
4. Double-click DevOverrideEnable, set the Value data to 1, and click OK.
5. Restart your computer or restart the relevant application processes for the changes to take effect.

Effect of System-Wide Redirection

When DevOverrideEnable is set to 1, Windows honors .local redirection files and redirection manifests globally across the system. This allows an application to load a DLL placed directly in its directory or a specified override path, even if that DLL is protected by the Windows KnownDLLs list or located in C:\Windows\System32.
