High CPU for multiple processes Microsoft 365

In the last several days I have noticed my laptop CPU fan blowing constantly. The culprit seems to be 4 identical processes using the same amount of CPU as each other continuously hovering at about 8-12%. This keeps the fan blowing 24/7.

The Task Manager shows the Process name as "Microsoft 365 and Office (32 bit)" and no Office applications are running. When I view the details the executable names are "odt____.tmp.exe" with the underscores representing some 3- 4-character hex value, e.g. C67A.

I can end the tasks but they come back after a time and the CPU fan turns on again.

What are these processes and can I turn them off?

TIA

BTW, I tried to include a screenshot, but the image upload doesn't work.

    I posted this before but the only way I have found to stop is to stop whatever is trying to update Office. Intune, another MDM, etc.

    I had six of them running, I was cursing Chrome for being bad after an update. Turned out to be this thing going on.

    After I killed them all and removed the files from c:\windows\temp, it created 8 such files again in C:\windows\temp, all files with date modified 21-11-2023 22:05 and it started one up.

    Thanks! I was being silly and looking in the wrong location. Found them all now. The ones which start to run with high CPU are all dated 21/11/2023 as per later post. They seem to be delivered in batches of about 50 once every four to six weeks (presumably when Office updates).

    After removing them, you have to update the Office Package. Hope that helps, cause I did it haha
