1. Was this issue present on Windows 10?

No, it was working perfectly fine. It stopped working when I upgraded to Windows 11.

2. Is there another overclocking tool installed on your system? Perhaps a preinstalled toll from Alienware.

Yes, I have Alienware Command Center installed, but it is disabled. It was already installed when I was using W10 and XTU was working fine back then.

3. Was the Intel® Extreme Tuning Utility (Intel® XTU) working on Windows 11 with the previous river version?

I was not using a previous version of Windows 11, I installed it when it was officially released. The first time W11 booted up it already showed the error.

4. Can you share the Intel® Extreme Tuning Utility (Intel® XTU) logs?

- Steps: Disk> tab view> hidden item check>program data> intel> Intel XTU> ctrl C> paste on the deskstop>right click on the file>send to> compressed zip>send 

I attached the logs.
