What Remote Desktop Connection does

Remote Desktop Connection lets you see and control another computer's screen from wherever you are, as long as both computers are connected to the internet or the same network. You type on your keyboard and move your mouse, and the other computer responds as if you were sitting in front of it. Windows includes this tool built in — you do not need to buy or read anything extra.

People use it to work from home on their office computer, help a family member fix a problem on their machine, or access files stored on a home computer while traveling. The connection is encrypted, meaning what you type and see stays private between the two computers.

Key Takeaways

  • Remote Desktop Connection is built into Windows and requires no extra software, but both computers must have it enabled in their settings.
  • You need the other computer's name or IP address, and the account password for a user on that machine, to connect.
  • The computer you are connecting to must stay powered on and awake — it cannot be in sleep mode or locked with a screensaver.
  • Home editions of Windows have limits: a Home computer can be controlled remotely, but cannot control another computer remotely.
  • If you cannot connect, check that Remote Desktop is turned on, that you have the right computer name, and that both machines are on the same network or both have internet access.

Checking which version of Windows you have

Remote Desktop works differently depending on your Windows edition. Windows Pro, Enterprise, and Education can both control other computers and be controlled. Windows Home can be controlled remotely, but the Home version cannot reach out to control another computer — you would need Pro or higher for that.

To find your edition, right-click the Start button, select System, and look for "Edition" in the window that opens. If you have Home and need to control another computer, you would need to upgrade to Pro, or use a free alternative like TeamViewer or Chrome Remote Desktop instead.

Turning on Remote Desktop on the computer you want to control

The computer you plan to control from a distance must have Remote Desktop enabled. Open Settings, go to System, then select Remote Desktop from the left menu. Toggle the switch to On. Windows will ask you to confirm — select Confirm.

Write down the computer name shown on this screen — you will need it when you connect. The name usually looks like DESKTOP-ABC1234 or your actual computer name if you set one. You can also find this by right-clicking Start, selecting System, and looking for "Device name" near the top.

Connecting from another computer

On the computer you want to connect from, press the Windows key and type "Remote Desktop Connection" into the search box. Open the app that appears. A small window will open with a field asking for the computer name or IP address.

Type the name of the computer you want to control — the one you just enabled Remote Desktop on. If you are on different networks, you may need the IP address instead. Click Connect. Windows will ask for the username and password of an account on that other computer. Type them in and click OK.

The remote computer's screen will appear in a new window. Your mouse and keyboard now control that computer. To return to your own screen, move your mouse to the top of the remote window and click the X button, or press Ctrl+Alt+Home to minimize the connection.

What to do if the connection fails

If you see an error message, start by checking the most common problems. First, make sure Remote Desktop is actually turned on on the computer you are trying to reach — go back to Settings and verify the toggle is On. Second, confirm you have the correct computer name or IP address. A typo here is the most frequent reason for connection failure.

Third, check that the other computer is powered on and awake. If it is in sleep mode or the screen is locked, Remote Desktop cannot connect. Wake it up and unlock it if needed. Fourth, if both computers are on different networks, make sure both have working internet connections. If you are on a corporate network, your IT department may have blocked Remote Desktop — ask them to enable it.

If you still cannot connect, try restarting both computers. Sometimes the Remote Desktop service needs a fresh start. If the problem persists and you need to help someone else, suggest they use a free alternative like TeamViewer or Chrome Remote Desktop, which work across different Windows editions and do not require as much setup.

Keeping your connection find

Remote Desktop sends your password over the network, so only use it on networks you trust. Do not use it on public WiFi unless you have a VPN running. Change the default port if you plan to allow connections from the internet — Remote Desktop normally listens on port 3389, and hackers know this. You can change it in the Remote Desktop settings, though this requires some comfort with Windows configuration.

Never share your computer name or password with anyone you do not trust completely. If someone else needs to control your computer, create a separate user account for them with a strong password, then delete that account when they are done. This prevents them from accessing your personal files.

Using Remote Desktop for work or support

If you work from home and need to access your office computer, Remote Desktop is faster and more reliable than uploading files back and forth. Open the programs you need on your office machine, and they run there — your home computer just displays the screen. This means you can use powerful software that your home computer might not have installed.

If you are helping a family member with a computer problem, Remote Desktop lets you see exactly what they see and fix it directly. Ask them to enable Remote Desktop, get their computer name, and connect. You can walk them through steps while watching their screen in real time. When you are done, have them turn Remote Desktop back off in Settings.

Frequently Asked Questions

Can I use Remote Desktop on a Mac or Linux computer?

Remote Desktop Connection is a Windows tool, but you can connect to a Windows computer from a Mac using the Microsoft Remote Desktop app from the App Store. Linux users can use Remmina or other open-source tools. You cannot use Remote Desktop to control a Mac or Linux machine from Windows — you would need different software for that.

What if I forget the computer name?

Go to the computer itself, right-click the Start button, select System, and look for "Device name" near the top of the window. You can also open Settings, go to System, and find it there. Write it down or take a photo so you have it when you need to connect remotely.

Does the remote computer need to stay unlocked?

Yes. If the screen is locked or in sleep mode, Remote Desktop cannot connect. Ask the person at that computer to unlock it and keep it awake, or set the power settings to never sleep while you are working. Once you disconnect, they can lock it normally.

Can two people use Remote Desktop on the same computer at the same time?

No. When you connect remotely, the person at the computer is logged out or their session is paused. They cannot use the keyboard and mouse while you are connected. This is a security feature to prevent two people from controlling the same machine at once.

Is Remote Desktop the same as screen sharing?

No. Screen sharing shows you what someone else sees but they keep control. Remote Desktop gives you full control of the other computer — you move the mouse and type, and they see what you are doing. Remote Desktop is more powerful but requires more trust between the two people.
