Cannot Set Priority in Task Manager on Windows 10 Fix

If you are an avid gamer and you are trying to play a high-end game on your regular PC that does not have matching specifications, can lead to a slow gaming experience. While you may experience low frame rates for the game, it can even crash at times when the game gets intensive. In such cases you can set the game’s priority to high using the Task Manager. You can also set the priority to high for any other process if needed through the Task Manager. This helps Windows to allocate a major chunk of its capacity for the game or the process.

However, the Task Manager may sometime return an error message that says Access Denied, thus, preventing you to change the priority of the game or the process. Sometimes, it simply doesn’t let you change the priority and this issue can occur with either some processes or all. Usually, the concern arises when the error occurs for all processes on your system and not just for one. If the error occurs for one process on different systems, then it’s an issue with the process.

Fortunately, there are a few ways that can help you fix the issue. Let’s see how:
