Often, users of personal computers, not delving into the intricacies of the device, and also not understanding the nuances of various programs, use only a limited part of the available functions in their work. This approach is very useful when there is little time left, but it can do a disservice if there are additional requirements or desires to do something in a new way.
If you don't want to figure it out on your own, but among your friends there are those to whom you could turn for help, then if you have a problem with your computer, "Remote Assistance" may well help you.

This feature of Windows is a standard operating system service that allows another user of the same operating system to remotely access your computer's files in order to help resolve your difficulties. You must fully trust the person who will help you, as he will have full access to yourcomputer, can view personal files, and more.

The application has been built into the system since Windows XP. It turned out to be so popular that it became part of later versions. In addition to its standard purpose, "Remote Assistance" is also used for remote training of someone, since when connected, it becomes available to work with someone else's desktop in the same way as with your own, and the person whose computer you are connected to will be able to see all the executed you actions on your computer.
If we consider the "Remote Assistance" of Windows 7, you will notice that it is somewhat different from its analogue in previous versions.

Using the Remote Assistance service in Windows 7
First of all, you should make sure that both the user and his future assistant have Windows 7 installed on their computer, and there is a Windows Live Messenger messaging program, otherwise the connection will fail. Next, start the Windows Live Messenger communication service and perform the login procedure (if you do not have a Live Messenger account, you should create it on the official website or directly in the program menu).
Next, press the key combination Win + R, in the window that appears without quotes, write "msra" and click "Enter". This will open the main window of the Remote Assistance service. Here you need to select the item "Invite someone to whom youtrust to help" and then click "Use Easy Connect". As a result, it will be possible to select the administrator in the list of contacts of the Windows Live Messenger program and send him an invitation. The future assistant must also open the program window and select "Help someone who invited you" together with "Use Easy Connect". After completing all these steps, the administrator will be able to remotely connect to the user's computer.
In the future, all these settings can be omitted, saving them as standard.
Thus, it is possible to carry out remote administration and provide computer assistance at a distance without additional programs installed, only by means of the standard Remote Assistance service built into Windows.
