MicrosoftHigh CPU Use on all Office Tools
MicrosoftChristianBergstrom , Thanks for the tip, I tried disabling "Optional connected experiences" but doesn't seem to change anything.
CPU (and hence power) use are high 100% of the time by all the office tools. In the Office Account pick, it says "Product Information, Subscription Produce Microsoft 365 for enterprise"
Any of the tools use ~15% of the CPU continuously. This just seems ridiculous, are there any diagnostics I can run to tell me what they are doing? Disk/Newtork/GPU are all low but CPU is not. If I run Word, Excel, PowerPoint and Outlook simultaneously, I get:
All doing nothing, just selected create new in all but Outlook which is just sitting at the in box. Iconifying makes no difference. This is maddening. Disconnecting from the net does nothing either, what could they possibly be doing to use that much CPU?
_Scot_ Hey! Found a very similar issue that includes doing an Office repair

ChristianBergstrom, thanks again. Tried the repair, tried removing and re-installing and unfortunately:

_Scot_ I did find a work around. If I disconnect from the net, start the tool then re-connect, it never goes into the high CPU use mode. Bizarre but I can live with it.
- Thanks for the update. Sounds odd. Wonder if it’s related to the telemetry settings, do you know if it’s enabled for you? https://docs.microsoft.com/en-us/deployoffice/compat/manage-the-privacy-of-data-monitored-by-telemetry-in-office
As you asked about a support tool previously. Maybe not applicable now as you reinstalled, but good to know!
