• Step 2: The CPU use tab can be found on the Process tab. To arrange the apps and services by CPU consumption, click on the CPU column.
• Step 3: Close all superfluous apps that are using a lot of CPU power to see whether that reduces CPU consumption.

Keep in mind that online browsers like Google Chrome are infamous for using up a lot of CPU power, especially when streaming content from video websites or playing music while using numerous open tabs.

• Control Background Apps

Too many background apps and programs could occasionally hog the CPU if you have too many running. To prevent this, you can completely stop some less useful programs from operating in the background. How? Read on.

For each app you don’t want to run in the background, repeat the process.

• Reverse The Power Plan To Its Original Settings

With Windows 11, you may select from a variety of powerful strategies to give either performance or battery life priority or to achieve a balance between the two.
