Launching Windows Programs in High Priority

June 2nd, 2007 @

Most likely you only have one CPU, yet multiple programs run simultaneously with little to no problems. But what happens when you want to run a program that seems to be stuttering out or that is time critical?

Every program that is run on your computer is assigned a priority to overcome this. Some programs may automatically change their priority. For example many CD/DVD burning programs run in high priority to prevent coasters. Programs are normally started at a ‘normal’ priority and you can adjust their priority via the task manager (cntrl-shift-del).

But what if you want to start a program with a certain priority? Enter Windows cmd.exe.

%windir%\\System32\\cmd.exe /c START /high program.exe

Simply replace program.exe with your program’s name/path and your in high priority heaven. Here are the other priorities copied and pasted from the help (cmd.exe /?).

LOW
Start application in the IDLE priority class
NORMAL
Start application in the NORMAL priority class
HIGH
Start application in the HIGH priority class
REALTIME
Start application in the REALTIME priority class
ABOVENORMAL
Start application in the ABOVENORMAL priority class
BELOWNORMAL
Start application in the BELOWNORMAL priority class
