Operating System WindowsAllows the setting of priorities CPU response la processes running on the system (present in Windows Task Manager). So if a process (firefox.exe, for example) has priority set "Hight", and iexplorer.exe is set priority level "Normal", response time to CPU for firefox.exe will be much lower compared to that of iexplorer.exe and other lower priority processes.
How to set process priorities (Set Priority).
1. open Windows Task Manager - Ctrl+Shift+ Esc
2. In the "tab"Processes"select the process whose priority we want to change, then do right click on trial. In the menu that opens we go to "Set Priority"and we choose the priority the desired selected.
In Windows 7 we have six levels of priority: low, Below Normal, Normal (default), Above Normal, Hight & Realtime.
3. Then click on the priority, a box will appear with a message:
Click: Change priority.
Be aware that the priority set in Task Manager processes do not remain so forever. After reboot, Will return the value priorities: Normal (value default for processes).
