RDP & VPS windows server is slow – troubleshoot and fix

Why Windows VPS & RDP server is slow?


There are many criteria that can make your VPS & RDP server run slowly. In this topic, we will check them one by one.


  1. First, you should check that your connection to the RDP is slow or the server itself is slow.
  2. Find that if there is a process or software in your server that has high resource usage or not.
  3. 2 processes are using the port of the remote desktop connection which by default is (3389).
  4. Viruses, Malware or Trojans have infected your server.
  5. You’re out of space on the server.
  6. Uninstall unnecessary software.
  7. Organize and clear desktop icons.
  8. Your server has fewer resources. (Upgrade your service)


  • 1- Maybe the remote connection to the server is slow, not the server.RDP
    You can view THIS LINK in order to resolve this issue.
  • 2- Open run (Windows key + R) and write taskmgr
    Remote desktop
    Here you can see the apps and processes, so easily you can close the tasks which are using high resources by clicking the end task.Remote desktop connection (RDP)
    Consider that 2 browsers at the same time can use many resources so it’s better to use one of them.
  • 3- If a second process uses the remote connection which is 3389 by default, it can occur conflicts and finally make your server run slowly.
    Open RUN by pressing the Windows button + R and type cmd, then press the enter button.
  • In CMD, write the command netstat –a –o to view the process and as a result, the ports which they are using.ports
    Note: Compare the remote connection port with PID (Process ID) of it.
    Note: A second PID should not use the RDP port.
  • 4- Maybe, your server is infected by Viruses, Malware or Trojans. In order to check this, you can download a powerful antivirus and anti-malware; personally I use the defender of the windows itself and antimalware like Malwarebytes which you can download for free.
  • 5- Open my computer and check that the drive in which Windows is installed on it is free of space or not because low space can decrease the speed of your server. Be sure to have a minimum of 400 to 800 MB of free space for instance in order to let the system keep temporary files.
    If it’s not free, maybe you have filled it by yourself or as a result, it has been filled by Windows temporary files.
    Have you filled it by yourself? so you can easily delete or move the additional files to another drive. If not, it has been taken by the Windows temporary files. In this situation, you can use the disk cleanup feature in order to remove the temporary files.
    Right-click on the drive which Windows is installed on it and use the disk cleanup option.
  • 6- You may have installed additional software which is installed on your server and you don’t use them. You can easily uninstall those apps in order to free up space and also to speed up the server as a result.
  • 7- Crowded desktop can easily decrease the speed of your server. Try to organize the desktop items and clean up the additional files in order to speed up the system.
  • 8- If none of the explained items speed up your server, maybe the resources of your server is low. You can easily open the task manager and analyze the situation of hardware.

If you feel that you’re out of resources, you can easily upgrade the server and speed it up.
