How To Set CPU Priority To Prefer Foreground Apps In Windows

Your operating system runs several processes in the background along with the foreground apps. However, it does not allocate equal resources like CPU time and memory to all processes.

By default, Windows gives slight priority to foreground activities. But, you may have unknowingly changed your setting to provide equal importance. Or you simply want to prioritize foreground apps even more.

There are a few ways to set CPU priority in Windows. They offer different options, so read carefully and pick one according to your need.

How to Set CPU Priority to Prefer Foreground Apps From System Properties

Using System Properties is the quickest way to set CPU priority to prioritize foreground apps. Here’s how you can do so:

Open the Run command (Win + R) and enter systempropertiesadvanced. It will direct you to the Advanced tab of System Properties.
Under Performance, click on Settings.
Go to the Advanced tab.
Check Programs and hit Ok.

However, this method still does not bring foreground apps to the highest priority. You’ll need to execute the next method for this purpose.

How to Set CPU Priority to Prefer Foreground Apps Through Registry Editor

You can also change the CPU priority using the Registry Editor. This method offers more options compared to the above.

You need to alter the DWORD value Win32PrioritySeparation to define the relative priority of foreground and background apps. To do so,

Enter regedit on the Run command.
Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl
Double-click on Win32PrioritySeparation.
Set its value to 26 on Hexadecimal base or 38 on Decimal.

How to Set Priority of Specific Process Using Task Manager

This method is more tiresome than previous ones if you want to set priority for multiple apps. However, you can prioritize individual apps instead of all the foreground or background apps at once. Follow the steps below to change priority using the Task Manager:

Press Ctrl + Shift + Esc to load the Task Manager.
Go to the Details tab and look for the apps.
Right-click on the process and hover over Set Priority.
Choose High or Above Normal.

Do this for all the processes you want and close the Task Manager.

How to Set CPU Priority to Prefer Foreground Apps With Command Prompt

You can also use the Command-line interface to set the priority for individual processes. However, since you need to know the name of the process, using the GUI might be more convenient.

Regardless, if you want to use the CLI,

Launch the Run dialog box and enter cmd to open the Command Prompt.
Type wmic process where name=”Process Name” call setpriority “Priority Level” and press Enter.

Make sure to replace “Process Name” with the full name of the process along with its extension and “Priority Level” to the priority you want, in this case, “High” or “AboveNormal” without removing the quote symbols.

As an example, wmic process where name=”vlc.exe” call setpriority “High”
