In February 2022, I filed a bug to Microsoft with my findings. However, I never got any reply from them. Since then, I was not updating any Windows 11 updates. So today, I restored my Windows 11 backup (I use Acronis) of February 2022 and updated my Windows 11 to the latest to check whether Microsoft has fixed it. It looks like they did. I am not getting any CPU overheating issues due to Windows updates. In the idle state, temp ranges from 41C-45C.
Also, unlike earlier, Windows 11 is not suggesting or installing the previous problematic updates anymore. (ie. KB5010414, KB5010474, KB5010386)
KB5010414 was not a preview update before, however now it's been marked as a preview update on the Microsoft site after they realized the issue. Refer to the screenshots below. So I believe this was the reason for CPU Temp (not sure though)

However, Now there is something else causing the CPU to overheat. It's the "Realtek HD Audio Universal Service." The CPU temperature reaches 84C to 87C while this service runs in the background. To fix this for the time being
either
- Kill it from the task manager.
- Disable the service from the startup I hope this helps.
(Note: My motherboard uses a Realtek ALC4080 codec. It could be a driver-specific error for this codec as well.)
