Do you know "Windows" shares the processor time between all running processes based upon their priority? If a process has higher priority, it gets more processor time compared to a process having lower priority.
But we can change process priority using "Windows Task Manager". Open Task Manager by right-clicking on Taskbar and select "Task Manager" or by pressing "Ctrl+Shift+Esc" keys together.
Once you open Task Manager, go to "Processes" tab, right-click on any running process and change the priority using "Set Priority" menu. You'll notice some system processes are set to "High" priority and almost all 3rd party processes are set to "Normal" by default.
Although you can change the priority according to your requirement, but the priority is not set permanently. Once you restart your system, Windows forgets your custom priority and assigns the process default priority.
So how to set a process priority permanent? Don't worry, here is the solution.
"Prio" is a free for personal use utility which solves the problem. It adds a new option "Save Priority" in context menu:

So now you can save the priority permanently.
It works in Windows XP, Vista and 7. It also adds a few extra features as mentioned below:
- Adds a new tab "Services" which shows the installed processes along with their status
- Adds another new tab "TCP/IP" which shows all established TCP/IP connections and all open ports
- Adds a new option "Silent Elevation" which allows you to execute a software with administrative privileges
You can download it using following link:

Trend Micro Internet Security Pro 2009 identified the download link as Dangerous.
Are you sure this is OK? It's something I've always wanted to find...

I get the warning to in Kaspersky 2010.

This program is safe to use. Microsoft Security Essentials and NOD32 didnt detect any harmful thing.
VM
I think it identifies it as dangerous because the program want to edit system files , or something like that....
VG
^^ Might be. It also installs itself as a system driver, that might be another case.
can you guys post full information about the alert?

Thank you for the great program, but I'm afraid that it fails to work on my machine. I've tried installing it twice, but it does not save the priority "permanently". It shows the "Save Priority" option, but it does not save it after closing the program in question. (E.g. Firefox.exe)
Can anybody please help me with my predicament? Many thanks in advance.

It does seem that the priority is changed, (As checking the task manager shows it uses more resources and it is slightly faster) but I can't be so certain: as when I close the program and run it again in the priority sub-menu, it has it's original priority. (Normal)
I appreciate the help and I apologise for the double posting, I just wasn't so sure if my original post was sent, as Noscript was currently forbidding Askvg.com. (I immediately allowed it as it's an excellent site for great software/tweaks.)

@Myrstidal
are you sure about that? do you check it after it has fully loaded?
or a min or a few seconds after double clicking on the FF icon?
