Windows 10: CxUIUSvc Service taking up tons of CPU

I have noticed that my battery drains quickly and my fans spool up quite often. I monitored task manager and "CxUIUSvc Service" pops up to the top quite often with very high usage. Does anyone know what this service does and how I can limit its usage?

Update makes games take up entire CPU

Hi,

Thank you for writing to Microsoft Community Forums.

To narrow down the cause we will require a few more information. Please reply with the following details:

• Which update was installed on the computer?
  
• What is the complete error message you get for
  srttrail.txt?
  

I would suggest you to post a screenshot of the Task manager to know which process is causing high CPU usage. Press
Ctrl + Shift + Esc to open Task manager. Click on
Details tab and then, click on CPU entry to align the processes in descending order and take a screenshot with all the listed processes.

Please refer how to include a screenshot
in your postto upload the screenshot.

Note: Make sure you don’t capture any personal information while taking the screenshot.


Meanwhile, you can try the troubleshooting steps mentioned and check if it helps in reducing the CPU usage.

Method 1: Disabling Service

Sometimes some service running in background can cause high CPU usage, we can try disabling the service and check for the CPU usage. Please follow the steps mentioned below:

1. Press and hold Windows + R key on the keyboard.
   
2. Type services.msc and click on
   OK.
   
3. Now, look for Superfetch service in the list and right click on the service.
   
4. Click on Stop to stop the service.
   

Method 2: Clean boot

To perform a clean boot on the computer, follow the steps from the article
How to perform a clean boot in Windows.

NOTE: Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program or process is causing the issue. Some of the Startup programs will not load after
performing a clean boot on the computer. However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.

If performing a clean boot fixes the issue then, please refer to the section
How to determine what is causing the problem after you do a clean boot
to check which program or process is causing the issue.

Hope it helps.

Please reply with the status of the issue, we will be glad to help you further.

How to control CPU usage of Sensor Services


Hello,
.
I have a little netbook/tablet with 2G of RAM. I found these services taking up a total of 40% to over 50% of my CPU's resources They are neccessary for things like sensing rotation (using as a tablet) and other things. They are:

• Sensor Service
• Sensor Data Service
• Sensor Monitoring Service

Can I configure the CPU usage or sensor frequency without disabling the service?

 

Antimalware Service Executable taking up high CPU for several hours!

No, it usually did not for me either, until today.

Posting system specs is a little off-topic, because my problem is that even though I do this step:
https://support.microsoft.com/en-us/...nder-antivirus

- The Antimalware Service Executable still runs high. I have a pretty good CPU and this has never been a problem until today.

My computer is neither new or old. It was installed 1½ years ago. I never had any problems until today.

I did this step:

That "note" is my problem... it still scans, and it is still scanning while I am writing this.

I already set the Exclusions to the Windows Defender path. Did not work either.
