Windows 11 TPM Requirement? Bypass it in 5 Minutes
So you have a $2,000 Core i7-6950X HEDT processor, which you thought would last forever, but Windows 11 Setup stands in your way with its steep system requirements that include TPM and Secure Boot. What do you do? With Windows 11, Microsoft introduced new requirements for compatible hardware, and these are purely software-only checks—nothing really requires it. Besides the much-talked about TPM 2.0 spec compatible hardware Trusted Platform Module as a system requirement, there's also new requirements for UEFI Boot, and installation on a GPT partitioned drive (no more MBR boot for Windows 11).
While these requirements do make some sense going forward, this walls off a lot of potential users, i.e. everyone without a TPM 2.0 add-on card, or those with processors older than 7th Gen Intel Core "Kaby Lake," or AMD Ryzen 2000 "Pinnacle Ridge" series. We have discovered a quick and easy way to defeat these checks during Windows 11 Setup, including for that nagging TPM 2.0, and Secure Boot. Here's a step by step guide for fresh installations.
Update Oct 7th: At the end of this article, which is focused on "clean installation", we added a method that lets you perform the upgrade of an existing installation to Windows 11, without any TPM. For this same scenario Microsoft offers a method that downgrades the TPM requirement from 2.0 to 1.2, our method works without any TPM and also relaxes other requirements, like memory size, UEFI and MBR.
Update Oct 10th: Improved the steps for the "upgrade" installation, to mention that updates to the updater should be turned off.
Step 1: Create the Registry Modification
After preparing your installation media (on another PC), open Notepad, paste the text below, save this file as "bypass.reg" on the bootable USB flash drive that's serving as installation media for Windows 11. You can also put just this file alone on a separate USB stick, the Windows installation environment will show it as additional drive.
Step 2 Boot from that Installation Media USB Flash Drive
Now, simply boot from that USB flash drive, run Windows 11 Setup, and proceed until you hit the screen that says "This PC can't Run Windows 11."
Here, click on the "back" button of the wizard (top left of the window), which takes you back to the previous screen.
Step 3: Invoke a Command Prompt
Press "Shift+F10" on your keyboard. This opens a Command Prompt window. Type "regedit" and hit Enter.
Step 4: Get Registry Editor to Pick Up that Registry File You Made
With Registry Editor open, get it to import the "bypass.reg" file that's been sitting on your USB flash drive.
Step 5: Proceed with the Installation
That's it! Close all windows, and proceed with the installation.
What Happened Here
The Windows 11 installation media, much like that of Windows 10 and Windows 8 before it, is essentially a bootable "live CD" of a Windows environment, with a singular purpose of installing Windows, or attempting to Repair your Windows installation. Logically, this environment needs the tools for such repairs, including a Registry Editor and a Command Prompt. It also has its own Windows Registry, which tells it how to go about installing Windows. With this Registry mod, you're making the installer overlook multiple system requirements, meeting, including "TPM Check," which checks for a TPM 2.0 compliant module (or Firmware TPM), whether Secure Boot (and its dependency of a disabled CSM) are met.

Bypass TPM and other requirements for Update from within Windows
Start the Windows 11 update software, click "Change how setup downloads updates" and select "not right now", or disconnect from the Internet before pressing "Next". The reason is that there's now a new version of the updater that disables the "back" button on the "Unsupported Hardware" screen. Click "Next", after some checking, a screen "This PC doesn't currently meet Windows 11 system requirements" appears.
Now open the folder "C:\$WINDOWS.~BT\Sources" and look for the file "appraiserres.dll", delete the file. Make sure to delete the correct file, there's several "appraiser" files in that folder.
Return to the Windows 11 updater (no need to restart it), click "back", and "next", done.

Windows Registry Editor Version 5.00Copy and paste the text, including the "Window Registry Editor Version 5.00" part, it should look like in the screenshot below. Also, make sure to save as "bypass.reg" and not "bypass.reg.txt", which can happen if you use notepad and have "Show file extensions" turned off in Explorer (the default).
[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]
"BypassTPMCheck"=dword:00000001
"BypassSecureBootCheck"=dword:00000001
"BypassRAMCheck"=dword:00000001
"BypassStorageCheck"=dword:00000001

You are not the target audience of the TPM requirement. Nor anyone able to use this workaround.
Yep looks like it's best to disconnect from the internet doing upgrading process
Back button was dead until I repeated without internet.
Otherwise might be short lived ?
Guess the other reg file has to be used after getting to 11 desktop ?
Yep but is there anything further to do after upgrading or all good ?
:D
Yeah everyone wonders where I get the Hi thing
Thought it would of even more controversial :roll:
Yep boom 11 I'll check for updates just to see if it dies lol
I/m using mbr only thing that qualifies is the 9940x I believe no uefi/ gpt/ secure boot/ tpm
Only the malicious software removal tool okay now was what we did malicious lol
Ran sfc /verifyonly found nothing corrupt already beats 10 lol
Yeah got an x99 haswell-e chip too no tpm chip though
Heck the way they did x299 there is no way to disable tpm once activated in bios because my x299 apex has not tpm port on it so :oops:
I did not see a tpm chip port on my z490 apex but it does have tpp or what ever it is in bios that can be enabled.
But yeah always on that bothers me a little seeing I will never use bitlocker or similar
