High CPU when using Word/Excel/OneNote and also online.

  1. I am running Windows 7 (about to upgrade to Windows 10) and Office 365 from my university-> Office 2016 programs installed on my laptop
  2. If I am working on Word (or One Note or Excel) while connected to the internet (but not using Word Online  etc through my Office account), it starts chewing up CPU , lap top starts overheating and I have to shut program down.
  3. When I try close Word (or One Note or Excel) it will eventually close the window but the program keeps running until I stop it via Task Manager.
  4. This only happens if I am using an Office product - Word, One Note, Excel - when I am online (usually via mobile broadband)
  5. This has been happening for about two weeks after some auto update
  6. I have run virus checks, removed all add ons (there was only one), run repair, uninstalled and reinstalled Office.

This is infuriating as I often access online databases, library catalogues etc as I work. I now cannot work while online which basically means I cannot work at all and have to revert to Office 2007.

Thanks in advance for your help.

    Hi KathieXX,

    Since this issue still exists, so you may need more powerful tools to detect this issue.

    I'd like you can try use the Microsoft Office Configuration Analyzer Tool 2.2  to see the where is the issue.And try performing clean boot. 

    In additon, please update you Office to the latest version and check if this issue still exists.

    If you have any further questions at this time, please feel free to contact me.

    Regards,

    Jerry

    Hi KathieXX,

    This seems to be an individual issue since we haven't get this kind report recently. I hope you can reinstall the Office client after Completely uninstall Office 2016 with the easy fix tool.

    If this issue still happens, as you said Windows 7 (about to upgrade to Windows 10), can you upgrade it, and check the running of Office 2016. Sometimes it is a solution for some factors that we do't know.

    Feel free to feedback here.

    Regards,

    Jerry

    Does the problem still occur if you start Word in Safe Mode by holding down the CTRL key while starting it until asked to confirm that you want to start it in that mode?

    If not, see the section dealing with Add-Ins in the KnowledgeBase article "How to troubleshoot problems that occur when you start or use Word" at:
