How to change a process priority in Windows 10
Method 1 – Set a process priority level using Task Manager
1. Right click on your taskbar and select Task Manager.
2. In the Task Manager, go to Details tab. On the Details tab, you will be able to locate all the processes currently on your system. Right click on the process for which you want to change priority level and go to Set priority and then select a level.
3. Close Task Manager.
Once you select a priority level, it should be applied to the process immediately. Note that setting the priority level to Realtime is often not recommended because it results in higher usage of system resources.
Method 2 – Set a process priority level using Command Prompt
1. Open Command Prompt.
2. Type following command and press Enter key:
wmic process where name="<PROCESS NAME>" CALL setpriority <PRIORITY LEVEL>
In above command, substitute <PROCESS NAME> with actual process name. And use the following numeric values for <PRIORITY LEVEL> you want:
- Realtime: 256
- High: 128
- Above normal: 32768
- Normal: 32
- Below normal: 16384
- Low: 64
For example, to set ‘explorer.exe’ process priority level to ‘Above normal’, one has to execute following command: wmic process where name="explorer.exe" CALL setpriority 32768. This result is shown in screenshot below.
3. Once you got ‘Method execution successful’ after executing the command, process priority level should be changed to what you’ve opted for. You can then close Command Prompt.
That’s it!
