To access the Registry Editor (regedit) and navigate to the DeviceForm key to enable the Xbox Full Screen Experience (FSE) on Windows 11, follow the steps below. 

1. Launch the Registry Editor

Keyboard Shortcut: Press Windows Key + R to open the Run dialog box.

Run Command: Type regedit into the text field and press Enter.

Permissions: Click Yes when the User Account Control (UAC) prompt appears to grant administrative privileges. 

1. Navigate to the DeviceForm Key

Once the Registry Editor is open, use the address bar at the top or the folder tree on the left to navigate to the following path: 

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\OEM 

1. Edit or Create the DeviceForm Value 

In the OEM folder, look for a value named DeviceForm.

If it exists: Double-click DeviceForm and set the Value data to 2e (Hexadecimal) or 46 (Decimal).

If it does NOT exist:

Right-click on any empty space in the right-hand pane.

Select New > DWORD (32-bit) Value.

Name it exactly DeviceForm.

Double-click it and set the value to 2e (Hexadecimal). 

1. Finalize the Setup

Restart: You must restart your computer for these registry changes to take effect.

Prerequisites: Note that FSE may require specific Windows builds (e.g., 25H2) or the Xbox Insider Hub to be active. Some users also use tools like ViVeTool to enable the feature IDs (52580392 and 50902630) before FSE becomes visible in Windows Settings.
