Generally CPU usage is not a problem in modern computers, unless there are very heavy programs running or in case of errors. For example, it may be that system processes such as svchost occupy 99% of the CPU or that the Chrome browser, due to a busted site or an error on a plugin goes to commit the CPU almost to the maximum or when you see interrupts of system use too much CPU.
Beyond these random events, if you often find that your PC suffers from slowdowns or blockages in the execution of programs, it can be useful, in addition to controlling the processes from the task manager (which opens on Windows by pressing the CTRL- keys together). Shift-ESC and on Windows 8 and 10 by clicking on More details ), the use of a tool that regulates the use of processor power .
In practice, we want to make sure that if a process consumes too much CPU, it is not terminated, but made less important than the others, so that the CPU can balance its load and work less for this process .
This is a mechanism that Windows already does automatically, so as to speed up the execution of high priority programs on Windows.
However, something better can be done to force the system to consume less CPU for a process when it exceeds a certain usage threshold.
For example, if one of the many Chrome processes consumes 40% or 60% of CPU, you can force Windows to downgrade the chrome.exe process by asking to make it less important and, consequently, avoiding that it can block or slow down your computer.
This mechanism works quite well using the small Process Tamer tool, one of many of this kind, free, simple and that works on Windows 7 and also on Windows 8.1 and Windows 10.
Then download Process Tamer from the Download button on the left on the Donationcoder.com website and install it using the regular procedure and without traps or sponsors.
The only thing to do to use the program forever is to register on the Donationcoder site and request the license key, always for free.
This thing must be done, if you like the program, within 10 days of installation.
The program must then be run from the Start menu and remains running in the background, visible from the icon in the notification area, near the clock (in Windows 10, if you do not see the icon, press the arrow upwards to find it).
Double clicking on the icon opens the configuration panel, where all active processes appear that use at least 1% CPU.
In the configuration tab, it is possible to decide the CPU threshold in use to make the program intervene which, by default, is 70%.
This is a very high percentage, which is fine on an old or underpowered computer, but which should be lowered to 30% or 40% on a normal computer.
When a process reaches the threshold, it is forced with low priority to consume less power .
You can also intervene on processes manually in Process Tamer, from the main processes tab, by clicking on the Explicit Rule column, where you can force a lowering or an increase in the priority for that process.
Depending on the computer on which it is used, Process Tamer can have a more or less excellent effect on general performance and if for some it is superfluous or useless, in other configurations it can really solve the situation.
This type of program has several alternatives, including a very famous and powerful commercial program called Process Lasso and a similar free one to raise the priority of processes and increase CPU performance .
