Can you tell if someone is remotely accessing your computer?

“Sometimes I use Remote Desktop to remotely access my office computer and complete my work, and sometimes I let my friends or technicians remotely access my computer to troubleshoot my computer problem. I wonder if they can access my computer without my permission since they’ve already had the credentials. If they can, then how to tell if someone has remote access to your computer?”

Remotely Accessing My Computer

How to detect remote access to my computer

The Windows built-in Remote Desktop has been widely used by many users. Some users may have the above-mentioned concern. Remote Desktop has been considered unsafe for 1) the client computer can remotely access the host computer even Remote Desktop is not running on the host computer; 2) the client computer can save the credential and achieve remote access without the permission of the host computer.

Here the good news is that you can always tell if someone has remote access to your computer. Because if a computer is remotely accessing your computer, then the screen of your computer will be locked, which means no one can remotely access your computer without letting you know it. This is what happens when someone remote access your computer.

When you unlock the computer, the remote connection automatically gets disconnected. So basically, no one can remotely access your computer without you knowing it. But if you need to leave your computer alone and don’t let anyone access it, you can disable the remote connection and enable it when you need it later. Here is how to disable remote connections.

Step 1. Press WIN + R and then type in “sysdm.cpl” to open the System Property.

Run Command Sysdm.cpl

Step 2. Switch to the Remote tab. Under the Remote Assistance section, clear the Don't allow remote connections to this computer option. Then click Apply and OK.

AnyViewer: Safe & secure remote desktop software

AnyViewer is the free and fast third-party remote desktop software for Windows and iOS devices. The advantage of AnyViewer over Remote Desktop is that the client computer can’t remotely access the host computer if AnyViewer is not running on the host computer. You can set AnyViewer to not start with Windows, then no one can remotely access your computer unless you open the program.

Not Start With Windows

AnyViewer provides you with two connection methods. The first is to send a control request, which means the controller needs to ask for permission from the recipient to achieve remote access. The second is to input the security code, which is set by the recipient in advance and then given to the controller to achieve unattended remote access. If the controller is not very trustworthy, you can also give him the temporary security code.
