Windows Remote Assistance is a feature of Windows XP and later that allows a user to temporarily control a remote Windows computer over a network or the Internet to resolve issues without directly touching the unit.[1][2]
In Windows Vista, Remote Assistance is a standalone application and does not use the Windows Help and Support Center or Windows Messenger. It is based on the Windows Desktop Sharing API.[citation needed] Two systems administrators can simultaneously connect to a single computer. Remote sessions automatically reconnect after restarting the computer. It also supports session pausing, built-in diagnostics, chat, file transfer and XML-based logging. It reduces bandwidth requirements for low-speed connections. NAT traversal allows a session to be established even if the user is behind a Network Address Translation (NAT) device. Remote Assistance is configurable using Group Policy and supports command-line switches so that custom shortcuts can be deployed.
Helpers can open multiple simultaneous sessions—one for each remote computer. However, users can have only one RA session waiting for a connection.

Connect invitations can be sent to multiple recipients—any of which may connect. All subsequent connect attempts will be blocked until the first helper disconnects, after which another helper may connect. If the user disconnects the session, the RA application terminates and no further connections areallowed.
In Windows 7, WRA is based on RDP 7 and uses PNRP when connecting using the Easy Connect option.[3] With Easy Connect, only a password needs to be shared instead of an invitation file, and two computers can establish a peer-to-peer connection over the LAN (Local Area Network) or the Internet without a relay server.
