Windows 10: High CPU and Battery usage by Windows System task

Hello,


I have a Dell Inspiron with an i5 processor and 8 gb Ram. Recently I swapped my HDD for a new Samsung SSD because the computer would freeze and my disk usage was perpetually at a 100%. Ever since I reinstalled windows, my laptops battery life has gone from an average of 4-5 hours and now finishes in under 2 hours with minimal usage. Each time I open task manager, the "System" task eats up an average of 30% of the CPU and always has either very high or high power usage, which I suspect is the reason for the massive decline in battery power, instead of the normal improvement when someone shifts from an HDD to an SSD. Any help would be much appreciated. Thanks!!

:)

 

high cpu usage

After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
programs and find no viruses. Any suggestions? Thanks.

 

Windows Explorer high CPU Usage in Windows 10

To further troubleshoot the issue, we suggest checking the Task Manager again to see what are the
applications that have high CPU usage. To do this, follow the same steps you did from the previous reply:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

However, based on your response above, it seems that you may need to create a new user account again and just install your apps manually instead of copying them as your
previous user account might be corrupted.

Once your done with the steps, please let us know how it goes.

 

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.
