When I look at
[HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0]
I see what is at the bottom of this page (it means "DWORD value (32 bit) not valid")
The content is this one

I saved that key some time ago and this is what was contained in it

That string was then (how?) changed from
"FeatureSet"=dword:21193ffe
into
"FeatureSet"=hex(4):fe,3f,19,21,00,00,00,00
I tried to restore the original key changing the registry key writing on it, but after the PC is restarted, the "invalid" key represents again (maybe it is restored taking the new key from somewhere else)
Also processors 1, 2, 3 have that same "invalid" key.

Hi,
Thank you for the information. Modifying or correcting key in the registry is very complex it may cause serious problems on your computer once you've done something wrong.
What we can advice is to seek help on our Technet forum, it is better suited for the IT Pro audience on Technet to give you information and steps on how to correct registry key.
Let us know if you have other concerns.
So far I have no visible problem, no error messages, nothing.... but I am wondering if that particular key is used by the Operating System.
As I wrote, if I correct that key and write into that key the old content (so that I don't see any error warning in Regedit), when the PC is restarted that "not valid" key reappears again.
Hello,
Before we rectify your concern, can you tell us if you are experiencing any issues on your computer? Are you having performance issues on your PC or are you getting any error messages when using it? If not, then there's nothing to worry about it. We advise that you keep the Windows registry as it is. Modifying the registry incorrectly may cause serious problems on your computer.
Let us know if you have any other concerns.
