Thanks for the reply and update, that's all I wanted. The silence on Aida's part over this issue has been deafening for to long.
I'm a Windows insider running the latest build of Win 11 and yes I have been banging on Microsoft's door with even greater ferocity than I did on your door, but my banging on your door achieved the desired effect, a response!
As others have stated, MSI Afterburner, HWinfo are reporting correct CPU usage, whether they are using work arounds or not is irrelevant at least they report CPU usage.
My PC specs are listed in my post, I would say that the components are common in a lot of builds. Given the number of people reporting this problem I find it difficult to accept that you cannot replicate the problem.
Microsoft's response was typical, not enough upvotes so not a big issue. But I will continue to bang loudly on their door.
But once again, thanks for the response.
