Find Wireless Display Receivers in Windows Regedit

Windows stores details regarding wireless display connections, Miracast receivers, and projection profiles across several dedicated registry paths. This guide outlines the exact locations in the Windows Registry Editor (Regedit) where authorized wireless display receivers, paired Wi-Fi Direct devices, and system projection policies are saved.

Opening the Registry Editor

  1. Press Windows Key + R to open the Run dialog box.
  2. Type regedit and press Enter.
  3. Select Yes when prompted by User Account Control (UAC).

1. Miracast Receiver and Authorized Profiles

The primary registry location containing settings and authorized profile configurations for the built-in Windows Wireless Display (Miracast) receiver is:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MiracastReceiver

Within this key, you will find parameters determining how the device handles incoming projection requests, including: * ConsentSucceeded: Records authorization states for incoming connections. * Secondary keys (such as KnownDevices or AllowedDevices): When configured, these subkeys store the unique hardware identifiers and permissions for previously paired or authorized transmitting devices.

2. Paired Wireless Display Devices (Wi-Fi Direct & Miracast)

To view the hardware-level profiles of authorized or paired wireless display receivers and adapters, navigate to the Software Device enumerator keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SWD\WiFiDirect

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Miracast

Each subkey under these paths corresponds to a specific wireless display adapter, TV, or PC that has established a projection relationship with your system. The entries include device instance paths, friendly names, and interface configurations.

3. User-Specific Projection and Connected Device Profiles

For connection histories and profile metadata specific to the active user account, check:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ConnectedDevices

This key contains cached identifiers and connection states for peripheral displays and cast receivers paired through the Windows Action Center or Settings app.

4. Enterprise Projection and Connect Policies

If wireless projection permissions and allowed PIN profiles are managed via Group Policy or Mobile Device Management (MDM), the enforced configuration resides at:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Connect

Key values in this location include: * AllowProjectionToPC: Controls whether the machine can act as a receiver. * RequirePinForPairing: Enforces authentication profile levels (e.g., First Time, Always, or Never). * AllowProjectionOverPCNetwork: Manages projection over standard infrastructure networks.
