It has been asked several times if there is a way in Windows to adjust process priority on the fly automatically. Generally you can install software such as process lasso or such.

However there is a command line option to so the same thing using wmic. Apparently it has been around since XP... I recently learned about it when doing some other things. So I figured I would share the info.

The command line syntax:
wmic process where name="AppName" CALL setpriority ProcessIDLevel

The customary notepad example setting it to "Above Normal":
wmic process where name="notepad.exe" CALL setpriority 32768

Idle:		64
Below Normal:	16384 
Normal:		32 
Above Normal:	32768
High Priority:	128
Real Time:	256

On XP/2003 I had to run wmic by itself first where it stated "Please wait while WMIC is installed.

At the moment I'm trying to work out how to use the Task Scheduler to set the science app priority up when the machine is idle and then return them to low when not idle.

Ah.
The hidden feature`s of an operating system . . .
If only we knew what they were,
where they iz
And wot to do with them once we have found them :¬)
For better or worse ....

Yeah - almost as well documented as my phone apps. God, bad programmers ought to have their own personal place in Hell.

You can use Task Manager, it is probably quicker and less error prone; and they both call the same API.

Go to the Processes tab, right click the process you wish to change the priority of...

Our friend Fred's priority tool does a wonderful job of setting the priority of Seti apps to whatever level you wish. And does so automatically every time a task is finished and a new task launches.

This information is more for those that ask how to change the to process priority automatically. Other than telling them to "install 3rd party software".

Since I stumbled on it while doing other things & no one had mentioned it before, that I could find, I figured someone might have a use for it.

A full write up about all the various ways of controlling the science app processes would probably be more informative when I get around to putting this up on my webserver.
