A remote assistance controller serves as an intermediary between a user requesting remote assistance and a remote assistor. A remote assistance policy determines what the remote assistor can see or not see on the requestor's computer system, and may additionally determine allowed or disallowed actions by the remote assistor. The remote assistance policy may be defined by the requesting user, or can be a default policy for the remote assistance controller. The remote assistance controller generates views for the requestor and for the remote assistor. When the remote assistor requests an operation on the requestor's computer system, the remote assistance controller checks the remote assistance policy to determine whether the remote assistor is allowed to perform the requested operation. When the requested operation is allowed according to the remote assistance policy, the remote assistance controller allows the requested operation, and refreshes the views for the requestor and the remote assistor.
