Hi Mazi,

I understand the reason why you need low the priority of the default
processes. My suggestion is to keep the priority of default processes
unchanged. Let us specify the process you want to run in a higher priority.
I think it will be easier to be implemented.

To run a program and specify its base priority at a command prompt, use the
following syntax:

 "start /<priority> <program>" (without the quotation marks)

The following sample steps describe how to run Notepad with Realtime
priority:

1. At a command prompt, type the following line, and then press ENTER:
 " start /realtime notepad.exe" (without the quotation marks)

2. To verify the priority level, press CTRL+ALT+DELETE to open the Windows
NT Security dialog box.

3. Click Task Manager.

4. Click the Processes tab.

5. On the View menu, click Select Columns, click to select the Base
Priority check box, and then click OK.

6. In the list of processes, locate Notepad.exe and confirm its base
priority level.

For the documentation, you may read the following article in Microsoft
Knowledge base:

191771 How to Alter a Program's Base Priority at a Command Prompt

Have a nice day!

| Thank you for your suggestion. I will try to see if I can manage to
| set/change priority through the Windows NT Registry on my Win2k3 server.
| However, I don't know which one is the base process to set/change and
would
| appreciate if anyone out here can tell me.
|
| As with lower priority, what you said is true; however, if I have all
| processes set/change to "BELOW NORMAL" priority, I don't any difference in
| responsiveness of each process. That way, I can introduce any other new
| processes that will require a better responsiveness with a higher
priority.
