Most windows operating systems include a build in Remote Desktop Client application.
Windows 7 and below
In windows 7 go to Start->All Programs->Accessories->Remote Desktop Connection or Start->Run and type mstsc and hit enter.
Use Start Search to search for remote. This time, select Remote Desktop Connection from the default Apps results list.
If this is the first time you’ve run RDC, you’ll want to configure some options. So click Show Options to reveal a more complex, multi-tabbed UI.
There are many options here, but you should at least review and configure the following information:
Computer: On the General tab, you will need to enter the name of the computer to which you’ll be connecting. You named your PC during Windows 8 Setup, but you can rename it later, or view the current name, by visiting the same System Properties control panel you used earlier. If you are using the same sign-in on each PC, you can leave the User name field blank. Otherwise, enter the user name you wish to use; you’ll be prompted at sign-in for the password.
Display: On the Display tab, you can choose between a full-screen interface (which will use the native resolution of the connecting PC, not the remote PC) or between several resolutions for a windowed interface. You can also change the color depth of the remote session, which can impact performance.
To test the connection, click Connect.
As the connection is made, you’ll be prompted to sign-in with the account password. You can choose whether to remember the credentials, which means you won’t need to enter this information in the future.
This one time, you will also see a dialog warning that RDC cannot find a trusted certificate for the remote PC. Select “Don’t ask me again for connections to this computer” and then click OK.
Finally, the connection is completed and the remote PC will appear (either full-screen or in a window, depending on how you configured it), and you’ll be signed in to that machine.
Click Start->Run and type 'mstsc' without the quotes and hit enter. If no window appears then goto 'installing the remote desktop client' section below otherwise see the steps listed above for Windows 7 & 8.
