Change process priority for all running instances


The following script sets all processes with a matching filename to different priorities.

Im my case I am using this to change the priority of my Minecraft server between high and belownormal depending on whether I’m just running the server or managing it. I had to set the same CPU priority for all running instances of the same processes quick and easy.


Change blue to the software you are using and red to the priority to wish to use. Paste code into notepad (or a better replacement such as Notepad++) and save as a *.bat file. Add to schedule or as a shortcut.

You can for example replace java.exe to explorer.exe if you wish to prioritize moving/copying files.

Batch Code

set pid=
FOR /F "tokens=2" %%i IN ('tasklist ^| Find /i "java.exe"') DO CALL process -p %%i high
goto :EOF

Place this in the same folder as the batch script or in your windows folder for global use.

    If you want to change ALL your process to Low. Run this batch as Administrator:

    set pid=
    FOR /F “tokens=2” %%i IN (‘tasklist ^| Find /i “.exe”‘) DO CALL wmic process where ProcessId=%%i CALL setpriority 64
    goto :EOF

    Somehow “CALL process” doesn’t work for me.

      Where it is 64 after setpriority you can change your desire priority following this list:
      Idle: 64
      Below Normal: 16384
      Normal: 32
      Above Normal: 32768
      High Priority: 128
      Real Time: 256
