Windows 7: Remote assistance – Black screen during elevated rights

By default you get a black screen when you offer remote assistance and run for example an application with elevated rights which is frustrated for IT support. In this post I will show you the two actions you must take to overcome this unpleasantness.

What Microsoft says about this:
It is not recommended that you start a program as an administrator in a Remote Assistance session. In this situation, the user can disconnect the Remote Assistance session at any time. Then, the user can continue to use administrative rights to run the program. To perform administrative tasks on a client computer, you may use a Remote Desktop Connection. 

To overcome this:

  • Change UAC policy

    Computer Policies\Windows Settings\Local Policies\Security Options\User Account Control\User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop

    UAC_Policy

    If you enable this policy setting, requests for elevation are automatically sent to the interactive desktop (not the secure desktop) and also appear on the remote administrator’s view of the desktop during a remote assistance session. This allows the remote administrator to provide the appropriate credentials for elevation.
