How do I set Program's priority ?

I want to run a CPU bound application in my computer (over windows).

But I don't want it to disturb me from working in the computer.

Each time I run the application I choose to lower the priority of the application.

It's not comfortable & sometimes the priority is not low enough.

Is there a way to mark the application as a low priority application ?

Thank you.

NOW, right click the program you want to operate and provide it with the priority you want...

you could run it as a service in order to automate startup and setting the priority.

more on running as services :
If youed have the ability to run the application via right-click on it and from the menu youed choose the priority you want to run it, is that OK?

Cyber, I tried to rightclick my application, I don't see any option to choose the priority.
When did you mean ?

"Windows 2000 is designed to run applications and services at different priorities. System priorities are how much CPU time a program gets. For example, a high priority program gets more processing time than a low priority program and will thereby run faster.
While application priorities can be set from the command line by typing:

START /[priority] [program]

I have created an Explorer context menu add-on which allows you to change a program's priority. Simply save the following as a .REG file, merge it into the Registry, and then right-click on your desired application to select its priority level from the menu:

-----Begin cut & paste here-----
Windows Registry Editor Version 5.00


@="Start &Realtime priority"

@="%systemroot%\\System32\\CMD.EXE /C START \"XQSHP\" /realtime \"%1\""

@="Start &High priority"

@="%systemroot%\\System32\\CMD.EXE /C START \"XQSHP\" /high \"%1\""

@="Start &Below Norm priority"

@="%systemroot%\\System32\\CMD.EXE /C START \"XQSHP\" /belownormal \"%1\""

@="Start &Low priority"

@="%systemroot%\\System32\\CMD.EXE /C START \"XQSHP\" /low \"%1\""

------End cut & paste here------"

Give it a try...
