How to Completely Disable ‘Projecting to this PC’ via Group Policy in Windows 11

Windows 11 includes a feature called “Projecting to this PC,” which utilizes Miracast technology to allow other wireless devices (like smartphones, tablets, or other Windows computers) to project their screen onto your PC’s monitor. While useful in a conference room setting, this feature requires your device to act as a wireless receiver, constantly broadcasting its availability over Wi-Fi Direct. In corporate environments, secure facilities, or crowded public networks, leaving this receiver active exposes the machine to unsolicited connection requests, screen-mirroring spam, and potential wireless exploitation vectors.

This guide explains how to completely disable the Projecting to this PC feature system-wide using the Group Policy Editor in Windows 11, ensuring the machine never advertises itself as a wireless display target.

Disable Projecting to this PC via Group Policy

To enforce a strict block that disables the Miracast receiver daemon and prevents users from turning it back on via the Settings menu, we must deploy an administrative template. Note that this requires Windows 11 Pro, Enterprise, or Education editions.

1. Log into Windows 11 with an Administrator account.
2. Press the Windows Key + R to open the Run dialogue box.
3. Type gpedit.msc and press Enter to launch the Local Group Policy Editor.
4. In the left-hand navigation pane, strictly follow this exact path:

   Computer Configuration > Administrative Templates > Windows Components > Connect

5. In the right-hand pane, locate the policy named Don’t allow this PC to be projected to.
6. Double-click the policy to open its configuration window.
7. Select the radio button next to Enabled. (Note: You must Enable this policy to disable the projection feature).
8. Click Apply, then click OK.

Verify the Configuration Lockdown

To enforce the change immediately across the system without requiring a full reboot, open an elevated Command Prompt and execute gpupdate /force.

To verify the restriction is active, navigate to Settings > System > Projecting to this PC. The entire settings panel will be completely greyed out and unclickable. A message stating “Some of these settings are managed by your organization” will be displayed at the top of the window. The underlying Wi-Fi Direct services responsible for broadcasting the PC’s availability will be neutralized, guaranteeing that no external device can discover or attempt to connect to your monitor wirelessly.
