Windows 10: Windows Logon GUI application causing high CPU usage!?

So the problem is as it says, when i start up my computer everything works smooth and fine, but then i hear the ventilators working as if the computer was using alot of CPU, with nothing actually running... then I open task manager and first thing that shows up is that "Logon GUI Application" is using about 70-80% of my CPU??? and after a second, It disappears and I hear my ventilator slowing down. This really makes 0 sense to me... Help!

Thanks in advance

WIN10 1703 update cause Explorer.exe high CPU usage

Hi,



Glad you reached out. First, we would like to know if Explorer.exe
is the only cause of high CPU usage. Because the common cause of high CPU usage are the following:

- Windows 10 Memory leak after the update.

- Driver incompatibilities after the update.

- Multiple startup applications

We'll be waiting for your update.

 

Windows 10 Display Blinking with High CPU

After upgrade to Windows 10, experiencing flashing display and high CPU.

• At initial logon screen everything is normal - wall paper and logon screen display with no blinking
• After logon, fan starts as CPU usage spikes, cursor is accompanied by the spinning blue circle
• touchscreen does not respond to swipe to access Recovery/Safe mode for reboot
• able to get to Task Manager and Perfmon to see high CPU usage and explorer.exe is suspended

looking for suggestions on how to either fix or roll back to Windows 8.1

 

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.
