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.
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]
"BypassTPMCheck"=dword:00000001
"BypassSecureBootCheck"=dword:00000001
"BypassRAMCheck"=dword:00000001
"BypassStorageCheck"=dword:00000001
"BypassCPUCheck"=dword:00000001
Copy 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).
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.

If you need additional help, let us know in the comments,

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.

DeathtoGnomesThis cant be a permanent solution, it seems to easy.

I wonder if this is a way to let MS backpedal with TPM.
Either that or TPM will become a hard requirement sometime in the future :(

Hi,
TPM 1.2 is now the hard line.

Ya I have no plans on moving to Win11 anytime soon and it has nothing to do with the TPM issue - thanks for providing the fix, though, much appreciated. I expect cracked copies of Win11 that will be pre-configured to have TPM requirements disabled, but it'll be YEARS before I move to Win11. I'll probably be on an X299 XE cpu by the time I decide to move to Win11 anyway, lol.

I'm enjoying the use of Windows 10 Pro - updates are disabled. It is so nice not having anymore issues due to updates, well, at least on my gaming system. I make sure I have multiple backups of my plex server since it is only running Win 10 home edition and updates could still be a problem down the line.

I've got no intentions of moving to another Windows version and having to screw around with stupid shit that happens. I've dealt enough with it on Windows 10....You know, I never had update issues with Windows 7, Vista or XP.

Actually only need the TPM bypass mostly.

I just do the shift f10

Open Regedit

Goto that setup folder

Add key LabConfig

add dword BypassTPMCHeck

Hit back then forward.

Much easier to simply install linux and not have to bypass garbage code, or continue running 10 until finally moving to linux.

Screw windows.

Hi,
Well the tpm was lowered to 1.2 so there is still a requirement for tpm 1.2 it was not removed completely via ms article stating so which you state in your edit but not reflected in the title.

Whether it still works without tpm at all being enabled you would know better than I since I have not tried on clean or update.

ThrashZoneHi,
Still requires tpm 1.2 and ability to enable it
Or and operable tpm 1.2 chip or I suppose tpm 2.0 chip so scalpers rejoice.

That does not apply to this registry setting. It completely removes TPM checks.
W1zzardWhy?
Because ThrashZone is confusing the standard article for the installer with these regkeys, which act distinctly different.

As RTB mentioned, my reg file removes the check completely, it doesn't require TPM 1.2. Feel free to test in a VM

Thats just an extra application that you have to install then. Onedrive is built in.
