Issue: [Fix] High CPU and disk usage by Microsoft Office SDX Helper

Hello. I noticed that the Microsoft Office SDX helper is using sometimes up to 70% of my CPU power when I am not even using it. It is causing my PC to heat up and I cannot seem to find a solution, as it keeps reappearing every time I end the task. Any suggestions would be appreciated.

Solved Answer

Microsoft Office is an applications package, servers, and services for the Microsoft Windows operating system. This includes Microsoft Word – a text editing program, Excel – an electronic spreadsheet, Outlook – an email client, PowerPoint – a program for preparing presentations, and many other services.

Unfortunately, sometimes users experience some issues caused by Microsoft Office, like high CPU[1] and disk usage by SDX Helper. This process is used to securely download and update Office. Some people report experiencing up to 70% of CPU usage by sdxhelper.exe, and it caused their PCs to use fans at high intensity.

A CPU (central processing unit) is the brain of the computer that performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program. When the CPU usage reaches too high, the workstation might physically heat up as it strains to perform tasks, and you will be worried that it could crash the system.

This could be a result of many different things, for example, a corrupt or outdated Office installation. Another possibility is that your antivirus application is messing up with the process, so we recommend trying to temporarily disable your security software to see if it is at fault.

Troubleshooting manually could take a while because it is unclear what is causing the issue, so you can try using an automatic solution RestoroMac Washing Machine X9 to avoid going through all of the possibilities. The repair tool can identify the damaged system components, fix BSODs,[2] and registry issues by scanning the system. This software could also be used to free up space by clearing cookies and cache,[3] which should boost the device's performance.
