Start Program With Realtime Priority By Default

Clarifications

By default, Windows XP set to Normal priority every you open an application. The priorities are Realtime, High, AboveNormal, Normal, BelowNormal, Low.
So you need set it manually if you want to give an application to higher priority. Windows XP provides two ways to set it. First way, with Task Manager and command line.
First way, to use Task Manager, you need press Ctrl + Alt + Del keys together. Then click Processes tab, right click the application which will set to certain priority, click Set Priority menu then choose your priority. (To open Task manager you also can through Run menu (Start-Run menu), type taskmgr.exe in box).
Second way, with command line, click Start - Run menu then in box type start /priority_parameter application_exe_filename. Parameters are /low, /belownormal, /normal, /abovenormal, /realtime. For example if you want to put Microsoft Word to realtime priority, type start /realtime winword.exe then press Enter key.
Now your favorite application can run on higher priority so then your application can run more smoothly.

If you want a particular Windows application to always start with a base priority other than normal, you can use the Start command in a batch file to always launch that application at a higher priority. For example, if you wanted to run an application named PriorityOne at a high priority, you could create a batch file using the start command:

start /high c:\priorityone.exe

This command could be used to start the application at a high priority.

To run the command to have the application start in RealTime priority it would be like this.

start /realtime c:\priorityone.exe

The batch file could be added to either of these Registry paths so that it is started when a User logs on.

? HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

? HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

And the batch file and reg file can be copied to the workstations where it can be run to create the timer.cmd and add the Registry entry. add2reg.cmd

=========================

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Realtime"="C:\timer.cmd"
=========================

=========================

C: regedit /s def.reg
goto tim

:tim
set timer= C:\timer.cmd
echo start /realtime c:\priorityone.exe >%timer%
call C:\timer.cmd
