Overview of Remote Desktop and Windows Remote Assistance

 Remote Desktop
           Remote Desktop is used to connect to a remote computer and have the desktop of that remote computer displayed locally. When you connect, you sign in just as you would if you were sitting in front of the computer. This allows you to sign in and run apps just as a user would for troubleshooting.
           Some organizations also provide remote access for users by using Remote Desktop and the Remote Desktop Gateway on Windows Server 2012 R2. This allows users to control their own desktop computer remotely and have access to all of their data and apps.
When users connect remotely, you can allow the redirection of printers and local drives. Printer redirection allows you to print from an app on a remote computer and have it print on a local printer. Drive redirection allows you to save files from a remote computer on a local computer.
           By default, Remote Desktop is not enabled. You can enable and configure Remote Desktop in the System Properties or by using Group Policy. Any necessary firewall rules for Windows Firewall are configured when you enable Remote Desktop. And the local Administrators are allowed to connect remotely, but you can add any users or groups that are required. When you add users or groups, they are made members of the Remote Desktop Users local group that has rights to connect by using Remote Desktop.

Windows Remote Assistance
           Using Remote Desktop, we need to sign in to the remote computer to creates a session for your user account and disconnects a user that is signed in. we cannot view what the user is doing. But using Windows Remote Assistance to view the desktop of a computer when a user is signed in, and see what the user sees. You also can request to take control of the mouse and keyboard to perform troubleshooting. The ability to connect to an existing user session is useful for troubleshooting problems that might be related to user-specific configurations, such as permissions or settings in the user profile.
           We can invite remote assistance to a user on a remote computer, or accept the request assistance. When you offer remote assistance, you connect to a remote computer by name or IP address, and the user is prompted to allow remote assistance. When users request remote assistance, they can generate an invitation file that you open to connect, or you can use Easy Connect. Easy Connect requires you to enter a 12-character password that is selected by the user. Easy Connect works over the Internet if Peer Name Resolution Protocol is allowed through all firewalls.
           By default, Windows Remote Assistance is not enabled. You enable Windows Remote Assistance in the System Properties. There are no permissions to configure for Windows Remote Assistance because it is allowed based on the currently signed-in user who is allowing it.
