The i7-7700K meet the minimun requierments to run Win11. But its not suported, Why?

Hi, I have an i7-7700K. This CPU have TPM 2.0, It's compatible with Secure Boot, it have 4 core up to 4.2 GHz. It also is 64bit.  I don't know why this CPU is not supported by Microsoft to install W...

Sixpiece  What? The CPU already meets all the requirements, besides being chosen by MS to be excluded. It's not a question of coders, the CPU is strong enough, has TPM2.0 on it, there is NO reason no to consider it compatible. You make no sense,

Incorrect the job of the operating system is to make a common platform between computer hardware resources and common software so that a software developer will not have to code for every possible hardware variation. There is code that needs to be written for each and every cpu that the operating system will support in order to keep the system stable. The registers, and many other variances such as optimizing instructions for pipelines, etc. , are just the tip of the iceberg to show you the enormous complexity and testing and support that will not be paid for those using the intel i7 7700k and thus the reason that they have decided not to support the processor in the Windows 11 release. It doesn’t automatically work, but you can go right ahead and bypass this requirement but your system will not be stable, the functionality will be poor and you will not be able to go back.

    Even something simple like having to answer 1000 phone calls on this matter will cost them 20000$ and they cannot support this release for everyone in this matter for a lifetime.

    Sixpiece I'm not sure you understand how CPUs work. Intel i7 and i8 have probably 99.9999% same instructions. It's not because the cpu changes generation that it changes how it operates with its registers. More to the point, they support SOME i7, it makes no sense to not support all of them, your argument is completely wrong.

      and even simple things like say you wanted to get optane memory to work on certain optane chips... from 8th or 9th generation to 7th generation I can show you chips that would better on coffee lake or later than kaby lake... so obviously there are physical hardware limitations as well... that is not to say that they cannot code it but it's not necessarily financially wise for them to do so... especially considering that they already got your money and they would get themselves a nice big fat paycheque when either you come around or someone in your workplace puts your job on the line for not having it...

       

      take this review: notice that the Intel technology does not work for Kaby Lake...

       

      https://www.anandtech.com/show/14249/the-intel-optane-memory-h10-review-two-ssds-in-one 

       

      it's one of many examples, but it shows that there are differences... if you want to know your processor architecture and other dynamics obviously it can be forever detailed but for example, what technical documents you need can be obtained from Intel directly. You can see by spec analysis there is a significant difference amongst the processors everything from frequency to cache size, etc.. enjoy the article... In the example of this article only Whiskey Lake properly supports the technology described in the article. Which also makes another point, that it would create issues for hardware designers as well... for example, if someone wants to create a new peripheral device for Windows 11 compatibility they would have to further extend their reach to looking at making it so that it can be backwards compatible to that of the Intel i7. I will provide a simple example to make a point, if someone like myself has an older laptop that supports say USB 3.0 but not 3.1, then the person selling the peripheral or harddrive or device, etc., needs to ensure backwards comptability with USB 3.0. So now it's not only Microsoft who pays but third party product vendors and developers... which is sort of lesser of a point because for example, they have let's say my old laptop again which is designed for windows 10, it is only has 4 gb of ram, so Android Studio that is Windows 10 compatible only accepts 8 gb of ram and up. So I don't see why they cannot simply look at which resources are missing and then say well it's not going to work for those applications but there is the issue of coding and making it that way... which could even be bios updates and a whole cost issue with no incentive.

        So, what you're saying is that it's a miracle that ALL OTHER WINDOWS OS never ever had a requirement other than power for CPUs? Also, unix, linux, and more recently MacOS? You don't think its weird that all of a sudden only windows marks an imaginary limit to the cpu it can use? It makes no SENSE, windows 10 works on it, all other OSs work on it.

        You can explain it away all you want, there is NO technical reason why it would NOT work.

      nbelley there is no intel i8 , if you are such an expert and believe they are so similar the instructions then just go right ahead and simply bypass the restriction but I told you that they are not and you will have stability issues, functional working issues and it could even go as far as actually killing your cpu in the end.

       

      You could probably use reverse engineering, recompile the compiler, and do some powershell scripting to account for the differences but you will need to do this for every update as it goes along as well as thorough testing so that part could mean instability in the tests as well..

        I would request the technical documentation from Intel so that you are able to ensure it is working the way that you want it to and since you claim it is so easy to do, just do it yourself.
