Quick Assist

Helpers offering remote assistance can open multiple simultaneous sessions—one for each remote computer. However, users seeking assistance from helpers 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 are allowed.

Quick Assist is installed by default on Windows clients, but is not available on Windows Server 2008 R2 servers.[4] The name of the tool differs depending on Windows language, search for "Quick Assist" in the Start menu will locate the tool regardless of the language settings.

Quick Assist requests a code in order to match users to a session. This will allow the giver to access the computer of the receiver in Administrator mode while allowing the receiver to see the choices the giver made.

It uses TCP 443 and communicate with the following hosts:

The feature was first introduced in Windows XP as Remote Assistance and based on Remote Desktop technologies.[5] Remote Assistance in Windows XP is integrated into the Help and Support Centre UI and allows sending invitations to the support person by email, Windows Messenger or saving the invitation as a file and transferring the file across through other methods.[5] The computer can be controlled by both, the support person connecting remotely as well as the one sending the invitation. Chat, audio-video conversations and file transfer are available.[5]

Remote Assistance in Windows Vista

In Windows Vista, Remote Assistance is upgraded with a standalone user interface and based on RDP 6 and Windows Desktop Sharing API.[6] 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, for example, a router in a home network. Remote Assistance is configurable using Group Policy and supports command-line switches so that custom shortcuts can be deployed.

In Windows 7, Remote Assistance is based on RDP 7. An extra option to connect using Peer Name Resolution Protocol is added, called Easy Connect if IPv6 connectivity is present.[7] 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 Local Area Network (LAN) or the Internet without a relay server. However, Windows Remote Assistance does not support file transfer and clipboard sharing in Windows 7.[8][9]

Remote Assistance is installed by default on Windows clients, but must be added manually on Windows Server 2008 R2 servers.[10] Remote assistance sessions may be initiated using the Windows Remote Assistance application available on the Start menu under All Apps → Maintenance[11] or by invoking msra.exe from command-line interface.[12]

The original Remote Assistance is included on all releases of Windows 10 as well, but since the Windows 10 Anniversary Update, its Start menu shortcut is removed, effectively hiding it from the user. Instead, a new app called Quick Assist is added.[13] It has mostly the same functionality and a similar user interface with buttons called Get assistance and Give assistance. The design is like UWP apps. Unlike Remote Assistant, Quick Assist requires the support person to sign in using a Microsoft account before dispensing help.[14][15]

The Quick Assist binary is located at "C:\Windows\System32\quickassist.exe".

While Remote Assistance establishes a Remote Desktop Protocol (RDP) connection to the end user's computer (requires TCP port 3389 to be opened on the client machine and the firewall/NAT/router behind which the machine is), Quick Assist is cloud-based and requires one outbound connection from the helper's PC to the cloud service/Microsoft server, and a separate connection from the cloud service to the machine of the person getting assistance. There are no ports opened on the client device's firewall.
