WIN7 program /process priority level manual control

As intro i copy paste this

1 Idle
2 Normal
3 High
4 RealTime (n.a.)
5 Below Normal
6 Above Normal

Cannot set RealTime with this value, only with Task Manager.
And my question is why there is no tweak , or util program that works and offers old fashion process list and change of priority of the proces for that on off session.

There are several programs , include task manager who offers on paper that can do that but in reality it is non consistent.
One is weak to falling under the some level of cpu usage, other reset under the influence of unknown factor.

I don't need permanent , after reset , solution, just till reset solution.

Specific problem is software like vmware player who is just a shell who runs vmware core process.

Affinity of cpu cores is something else, with thread and smp hardware support.
Is that so beyond usual usage in today computer reality...squeeze CPU power for some project and limit other applications on machine.

Is there maybe problem with my win7, because my task manager holds settings only some tome, average half hour and then reset to default?

P.S. There are boost utils, that boost focus window with priority, but that is not very satisfying in general.

Task manager does exactly as it promises. It changes the CPU priority just for that process, nothing else. It doesn't resets after "some time" or anything, it just sticks.
Of course, any program can change its own priority and if enough privileges are given, other programs can also change them.

Most important question is, what problem are you trying to solve? Why do you feel you need to change CPU priorities?

When i have several programs, one with calculation, another with dumb user stuff, i want to prioritize simulation even in background, especially in background. I would like it in percentage but lvl as other way of handshaking of process is good enough.

In my situation it seems that vmware workstation 10 is doing his own priority settings not favorable for me, for example it says low priority, normal priority for image system, and another instance of set of priorities for whole program vmware, but somehow it is always reset to normal..

As vmware simulation of opsys is more demanding than my own system, i find that giving higher priority to vmware-vmx process is good solution for leveling speed of both, my boot system and my simulated system on vmware.

But that is just a trigger.
I had similar needs in past to force priority of some CAE programs even it is not critical, because more priority, less time in calc and front dumb apps are not affected.

I can probably find command string to start process of simulation with vmware vmx and image that i want, so questions are, can i override vmware's priority walking , or what is correct registry handling of that aim.
What is example of command string to change priority of existing process, or getting what level of priority it is currently.

It is a little strange that one app can be superior toward the whole opsys...
I understand local management, but superior above force priority settings (if they exist or why they don't exist)
