Windows Remote Assistance Registry Keys

Windows Remote Assistance allows users to temporarily view or control a remote computer over a network to diagnose and resolve technical issues. This article explains the exact Windows Registry paths and DWORD values used to enable, disable, and configure the Windows Remote Assistance feature using the Registry Editor (Regedit).

Primary Registry Key for Remote Assistance

The primary registry key responsible for managing Windows Remote Assistance settings at the system level is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Remote Assistance

This key contains the configuration values that dictate whether the feature is active and how remote helpers can interact with the machine.

Key Values and Settings

Within the Remote Assistance key, several DWORD (32-bit) values define the feature’s behavior:

• fAllowToGetHelp: Controls whether Remote Assistance is enabled or disabled.
  • 1 = Remote Assistance is enabled (allows invitations to be sent).
  • 0 = Remote Assistance is disabled.
• fAllowFullControl: Determines whether a connected helper can interact with the desktop or only view the screen.
  • 1 = Allows the helper to take full control of the mouse and keyboard.
  • 0 = Restricts the helper to viewing the screen only.
• MaxTicketExpiry: Defines the maximum duration an invitation ticket remains valid.
• MaxTicketExpiryUnits: Specifies the time unit for ticket expiration (e.g., minutes, hours, or days).

Group Policy Registry Path

If Remote Assistance is managed via Group Policy or if you want to enforce enterprise-level settings across the operating system, the settings are stored under the policy key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services

Under this path, the following values manage Remote Assistance:

• fAllowToGetHelp: Toggles the overall policy for Remote Assistance (1 for enabled, 0 for disabled).
• fAllowFullControl: Enforces full control permissions for helpers.

How to Apply Changes

1. Press Win + R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Remote Assistance.
3. Double-click the value you wish to change (such as fAllowToGetHelp), set its Value data to 1 or 0, and click OK.
4. Restart the computer or restart the Remote Desktop Services service for the changes to take effect immediately.
