Why do I need to set CPU priority?
Some people set background processes, so they only start when they are needed. However, that doesn’t mean that you won’t have numerous processes running in the background when you open an app to begin working. With each new app, you open, Windows opens several others. These are in addition to the apps that are already working from the moment you start your computer.
If you open Task Manager, you may be surprised to see the number of apps operating in the background and the amount of processing power they consume. Setting Windows to allow foreground apps priority when it comes to processing power will improve those apps’ ability to function.
Two Methods for Setting CPU Priority
Use the Control Panel
The Control Panel is the easiest method for assigning CPU priority to apps you are actively using.
Type “Control Panel” into the search bar without quotation marks. Click on the Control Panel option.
Click on “System and Security” in the Control Panel menu.
Click on “System” and then choose “Advanced System Settings.”
In the System Properties window that opens, make sure that the “Advanced” tab is selected. Under the “Performance” subtitle, click “Settings.”
When the Performance Options window opens, click on the “Advanced” tab. Under the “Processor scheduling” subtitle, Make sure to select “Programs” under “Adjust for the best performance of:” Now, click “Apply” and then “OK.”
Doing this tells the computer you want it to give priority to the programs you have open instead of any background processes that might be occurring.
Editing the Registry to Assign CPU Priority
Unfortunately, Windows 10 offers users few options for assigning CPU priority. Although editing the registry is a valid method of setting CPU priority, it should only be done with extreme care. Make sure you perform a full backup of your system before attempting to edit the registry. Even if you do this correctly, you may experience unwanted side effects.
First, press the [R] key and the [Windows] key simultaneously. The run box window will open. Type “regedit” without quotation marks into the run box and hit [Enter]. When you are warned about the app making changes to the registry, click “Yes” to continue.
From the list on the left select “HKEY_LOCAL_MACHINE” and then “SYSTEM.” Then select “CurrentControlSet” and “Control.”
Finally, choose “PriorityControl.” From the list that appears on the right, click on “Win32PrioritySeparation.”
In the window that appears, the current value data is set to “2” by default. Change this value to “26” and click “OK.”
Restart your computer by clicking the Power icon found in the Start menu and selecting “Restart.”
Adjusting your computer settings so that foreground apps get priority when it comes to processing power is relatively straightforward. You can use either of the two suggested options or use both of them if you wish.
