Intel suggests to also check this topic: https://answers.microsoft.com/en-us/windows/forum/all/i-have-4-cores-but-task-manager-just-show-1-core/98983e46-8f50-4416-9998-77019d02efd7 . But in my case, I have only 6 CPU in the device manager.

After looking at this post on the MS forum, it may very well be a problem with Windows 11 (go figure). There have been a number of various problems of late with Windows 11 and the Windows 11 updates. One of my favourites is the crashing of the Calendar app in Windows 11.

The weird thing is that the laptop BIOS reports 3 cores, so Windows has nothing to do here:
The BIOS version 3.12.1 is the latest atm, it was installed recently:

@JOcean thank you for your reply. But the check in the options is not checked:
So no processors number is set here.
The system was reinstalled from an official MS image recently.
My Windows 11 has all recent updates. All drivers are updated from Windows Update.
