Windows 10: Microsoft Office SDX helper- High CPU in background

Today while I was doing work my computer fans started whirring for seemingly no reason- all I had open was google chrome. I checked task manager and found on program, Microsoft Office SDX helper, was using large (as in 70%) CPU out of the blue. Worried that it would crash my computer, I hit end process and nothing happened, so I thought I had solved the problem. However, this evening went I went to do more work the same issue happened, and again SDX was the culprit. And now it just happened a third time.

I can't imagine what is causing it to do this. I had not opened any office programs since I last restarted the computer and it has not happened before today. For a short term fix, I uninstalled Office for my sanity and not needing to keep the task manager tab open all day. Does anyone know of this problem/how to fix this?

System and compressed memory background process persistently consuming high CPU resources

Hi,

Thank you for posting in Microsoft Community.

Please answer these questions to get more clarity on this issue:

1. Did you make any changes to your computer prior to this issue?

2. Which anti-virus program is installed on the PC?

High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

Refer these steps:

• Press Windows key +X, select Control panel

• Change the view by option on the top right to Large icons
• Click on troubleshooting and click on the view all option on the left panel

• Run the System Maintenance troubleshooter

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

Thanks.

 

Windows Explorer high CPU usage as Apps or Background Process...

3May2018...

Running Windows10 Home Ver 1709 latest OS Build on

Intel Core i5 CPU @ 3.8GHz.

Recently Windows Explorer has been running at high CPU usage 45% to 50%

Even when I am not using File Explorer - Windows Explorer runs as a Background Process as same high CPU usage...

First when will Microsoft stick to the new name File Explorer - instead of showing Windows Explorer as the app in the Task Manager...confusing :-(

Two - I saw someone else with the same problem and a ridiculous multi step cumbersome solution of creating another account (where Windows Explorer did not have high CPU) and then a painful exercise of trying to migrate all applications and files from one
account to the other.

Apparently the original user account may have had a corruption....

Are there any simpler explanations out there on how to fix run away Windows(File) Explorer???
