Enable remote computers to accept the incoming remote connection with PolicyPak's pre-configured PAK for Microsoft Remote Settings.

In these steps, we will show steps for IT Administrators so they can Enable Remote Assistance for end-users computers.

Launch Group Policy Management Console.
Right-click on a required OU and Create a new GPO.
Give the GPO a descriptive Name then click the OK button.
Right-click on the new GPO you just created, and select Edit option.
Expand the PolicyPak node under Computer Configuration and select the pre-configured PAK named “PolicyPak for Microsoft Windows 7 and Later for System Properties”
Right-click on the PAK entry and select the Properties option.
Select the Remote tab, and select the checkbox “Allow Remote Assistance connections to this computer” and then click the OK button.
Note: Make sure that the selection is underlined as shown in the screenshot.

Set-ProcessMitigation -Name msra.exe -Enable DisableExtensionPoints.

You can create two separate policy items:
