Preparing for Insider Preview Builds of Windows 11 - ***UPDATED 6/28***

if you don't have a tpm then you need to go ot the bios and look for and option named

PTT and enable it

now try to install w11 again

Intel PTT is basically thefirmware alternative to a the hardware based TPM

@antoniooninato,

Unfortunately many machines don't have TPM nor PTT and they are out of the game unless MS removes that requirement. 😒

Ok here's my 2 cents. LOL  

They said that TPM has been around for the last 5 - 7 years.  

“Almost every CPU in the last 5-7 years has a TPM,” explains David Weston, director of enterprise and OS security at Microsoft.

If that's the case, then those CPU's should be supported to be able to upgrade to Windows 11.  

My PC, which is 3 yrs old, has TPM2.0  And passes every requirement except the CPU.

I think Weston's tweet was referring to "CPU" in the generic sense, as a computer, not as a central processing unit. (Nine out of 10 people think a 'CPU' is a complete, assembled computer and only vaguely guess at what a 'processor' is.) It is my understanding that a TPM is a physical module that is installed in a motherboard, either soldered in at the factory or plugged into a TPM motherboard header. (One of my motherboards has a TPM header, but there is no TPM on the motherboard.)

So that's why you can have TPM enabled in the UEFI but your CPU still does not pass the CPU (processor) threshold that Microsoft has set. Speculation: With the case of so many relatively current Intel series CPUs not qualifying, it would lead me to believe the reason has do due with the multitude of security bugs endemic to previous Intel chip series due to the company's chip architecture shortcuts (my opinion on 'shortcuts').

They do not truly answer everyone here or the vast majority already know that to force the purchase of new computers they will make thousands of computers outdated simply for their liking. Developers are preoccupation they can't even do windows 10 works right now they want to put a thousand resources but it has to be their way.

Assuming that "they" in your comment is Microsoft, why would Microsoft want to force purchase of new computers? With the exception of Surface-branded computers, which is a tiny fraction of the PC/laptop market, Microsoft does not sell computers.

I will bow out as impractical for me as not even minimum as i have the i7/7700k,, No uefi/secureboot and just a TPM header and I dont plan on buying any p.c. in the future just upgrade my homebrew P.C. eventually..

It is complicated...

Two Rampage systems.  One has a 20 pin TPM socket and the other has the 14 pin one.  But no TPM installed. On my Insider Rampage system there are the usual switches for UEFI / Legacy, Fast Boot and several Intel switches for features and virtualization. I have the most current version of Bios but I have not found PTT and will likely not see the TPM option until I get a module.  Unfortunately, NewEgg is already sold out on ASUS modules so I will have to check a few other places.

I do not have the Win 11 ISO to install and currently the documentation out there does not like my 6 core i7 processor .  So it is possible that one or both Rampage systems will only run Windows 10 when Windows 11 is released.  I will probably stay with Win 10 if that happens as there was a significant cost in setting up those systems and  at least Windows 10 will be ok to use for a few more years when I will be ready do build something else.  It is a decision a lot of PC builders will have to make. It is OK to stay with Windows 10 if it does everything you need it to do.  One thing that the enthusiasts are looking at though is the ability to run Android apps as well.  They will need to decide if it worth the cost to update.
