Can’t Set Process Priority in Task Manager of Windows 10 FIX

Some computer applications, especially games and digital design tools, require mainframe resources to run smoothly. Many users' PCs might not be able to handle such processor-intensive applications, so they chose to increase the priority of the program using Task Manager.

The higher the priority, the more resources Windows dedicates to the program. While not recommended, increasing the priority is a temporary solution that will work for most users. However, in some cases, when you try to change Process Priority in Task Manager, it fails, and you get an error that says Access is denied.

If you run into this problem in a particular process, then it's the problem stemming from the program in question and you can't fix it (for the sake of your computer). On the other hand, if you can't set the priority of multiple processes, read through this guide to learn how to troubleshoot and force your computer to let you change process priority.

A. Go to Safe Mode

  1. Open the Start Menu, click the Power button, press and hold the Shift key and select Restart.
  2. Reboot PC could not set priority in Windows 10 task manager
  3. Now go to Troubleshooting > Advanced Options > Startup Settings and click on Restart.
  4. When the PC reboots, press F4 or F5 to enter Safe Mode.
  5. After entering Safe Mode check if the problem is still there.

If there is no problem in Safe Mode, chances are your settings or installed apps are causing this problem, so you can try disabling certain apps and check if this is correct. Is that helpful.

B. Disable/Enable User Access Control

1. Press Windows Key+ S and enter the user control. Select Change User Account Control settings.

2. Now move the slider down to never notify. Click OK to save the changes.

After doing that, User Account Control will be disabled and you can change the priority of your processes.

C. Make sure that Administrator has full control

1. Press the CTRL + ALT + DELETE key combination and then click on Task Manager.

2. Find the priority process you want to change.Right click on the process and choose Properties.

3. Go to the Security tab and click Edit.

4. Select Administrators and check the Full Control option under Allow Now, click Apply and OK to save the changes.

You can also give full control to the User group, but that comes with some minor security risks.
