Here's how you can install Windows 11 without TPM 2.0. If you want to install it on your computer using either official or unofficial ISOs, you may be out of luck if your computer does not support Trusted Platform Module 2.0 or TPM 2.0. An attempt to install Windows 11 on a PC lacking TPM 2.0 will end up with the following error: "This PC can't run Windows 11. The PC must support TPM 2.0." Fortunately, it is easy to bypass the stumbling block. This article will show you how to install Windows 11 on a computer that does not support TPM 2.0.
Upgrade to Windows 11 on a device without TPM 2.0
To upgrade an existing Windows setup to Windows 11, you can use either Windows Upgrade Assistant or Windows Media Creation Tool, which both Microsoft made available on October 5, 2021. You can also use the official ISO image by mounting it and running the
setup.exe app from the ISO file. However, if you hardware is not supported, the setup will stop.
In order to allow users to install Windows 11 on such devices under their own responsibility, Microsoft allows adding a special Registry key that makes Windows 11 ignore the CPU and TPM 2.0 requirement. By default, at least TPM 1.2 is required.
To upgrade to Windows 11 on a device without TPM 2.0, do the following.
- On the system you are upgrading, open the Registry editor by pressing Win + R and entering
regeditin the Run dialog.
- Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. If the
MoSetupfolder is missing, create it manually.
- In the right pane, create a new 32-bit DWORD value named
- Double-click the
AllowUpgradesWithUnsupportedTPMOrCPUvalue and set its data to 1.
- Now install Windows 11 over your Windows 10 or other version of Windows you have installed.
Install Windows 11 from Windows Update without TPM 2.0
If you try to install a Windows 11 on a device without TPM 2.0 using the Settings app > Windows Update, it will end with a compatibility error. it will show youa requirement to enable TPM 2.0.
To install Windows 11 downloaded from Windows Update, do the following.
- Open File Explorer and make sure it shows hidden files and folders.
- Go to the
- Open Windows Settings by pressing Win + I and go to Windows Update.
- Click the "Check for Updates" button and watch the "Panther" folder.
- Delete files
appreiserres.dllonce they appear.
- After that, Windows Update might show you an error. Dismiss it by clicking the "Retry" button.
- Install the latest Windows 11 build as usual.
This should allow to bypass the TPM 2.0 enforcement when receiving new builds via Windows Update.
Install Windows 11 Without TPM 2.0
You need Windows 11 installation ISO, a regular Windows 10 installation ISO, several commands in Command Prompt/PowerShell/Windows Terminal, and an ISO image editing tool like infamous UltraISO.
To install Windows 11 without TPM 2.0, do the following.
1) Convert Windows 11 install.wim to install.esd
- Download Windows 11 installation ISO (it is up to you where to get it,) and double-click it in File Explorer to open its contents.
- Open its Sources folder, find the
install.wimfile and copy it to any preferred folder.
- Now, launch Command Prompt, PowerShell, or Windows Terminal as Administrator.
- Enter the following command:
dism /Get-WimInfo /WimFile:X:\Path\install.wim. Replace
X:\Pathwith the path to the folder with the previously extracted
install.wimfile. For example, C:\Users\Taras\Desktop\install.wim.
- Next, find the index number for the SKU you want to install. For example, Windows Pro.
- Now, enter the following command:
dism /export-image /SourceImageFile:"X:\Path\install.wim" /SourceIndex:INDEX /DestinationImageFile:"X:\Path\install.esd" /Compress:recovery /CheckIntegrity. Replace X:\Path with the path to your
INDEXwith the index number for the desired SKU.
- Wait for Windows to complete converting wim to esd.
- Unmount (eject) Windows 11 ISO.
2) Replace install.esd in the official Windows 10 ISO
- Go to the official Windows 10 website and download Media Creation Tool. Use is to download Windows 10 ISO for your computer. Skip this step if you already have one.
- Open the downloaded Windows 10 ISO image in UltraISO.
- Delete the existing sources\install.esd file you see in UltraISO.
- Drag and drop the
X:\Path\install.esdyou have created onto the UltraISO window to place it instead of the deleted file.
- Click on Save or press Ctrl + S in UltraISO to alter the ISO image.
Now you have a fresh Windows 11 ISO file ready for installation on computers without TPM 2.0. Install it as a regular Windows 10.
Modify the ISO image without using UltraISO
If you don't have the UltraISO app, you can use Microsoft's official tool oscdimg, which is part of Windows ADK. Here's how you can use it to put the install.esd file with Windows 11 over the existing Windows 10 file in the ISO image.
- Double-click your Windows 10 ISO to mount and open it.
- Copy all files and folders to any preferable folder on your computer, say
- Copy your Windows 11
install.esdfile you have created and paste it into the
c:\ISOFOLDER\sourcesdirectory. Confirm the original file replacement.
- Open a command prompt and type
oscdimg -m -o -u2 -udfver102 - bootdata:2#p0,e,bc:\ISOFOLDER\boot\etfsboot.com#pEF,e,bc:\ISOFOLDER\efi\Microsoft\boot\efisys.bin c:\ISOFOLDER c:\ISOFOLDER\Windows11.iso.
Voila, you Windows11.iso is in the
c:\ISOFOLDER ready for clean install!
Bypass the TPM 2.0 requirement without rebuilding install.esd
One of our readers sent me advice that instead of completely rebuilding the ISO image, it is enough to replace
appraiserres.dll with the same file from Windows 10. For example, in this way.
- Open the Windows 11 image in UltraISO.
- Delete appraiserres.dll.
- Double click on the Windows 10 ISO file in Explorer to open its contents.
appraiserres.dllto the remote location in UltraISO.
- Save the Windows 11 ISO.
Replace appraiserres.dll in Windows 11 image with oscdimg
- Double click on the Windows 11 ISO file in File Explorer.
- Copy all content to c: \ ISOFOLDER folder.
- Double click on the Windows 10 ISO file in File Explorer.
- Take the
appraiserres.dllfile from Windows 10 and copy it with replacement to the
- Build the iso file with the command
oscdimg -m -o -u2 -udfver102 - bootdata:2#p0,e,bc:\ISOFOLDER\boot\etfsboot.com#pEF,e,bc:\ISOFOLDER\efi\Microsoft\boot\efisys.bin c:\ISOFOLDER c:\ISOFOLDER\Windows11.iso
Bypass the TPM 2.0 and Secure Boot requirements in the Setup program Registry
One more method is to disable the TPM and Secure Boot checks right before you install Windows 11, from its preinstallation environment.
As you may already know, modern Windows version load a minimal OS version, earlier known as "MiniOS", now know as Windows Preinstallation Environment. It loads the required set of drivers and starts the main Windows setup program.
You can modify its registry, so it won't perform TPM and SB checks. Here is how.
- Download and place this REG file to your bootable media with Windows 11, or on the hard drive.
- Boot your PC from that bootable media and set the language preferences.
- On the next page, select Install now.
- On the product key page, press Shift + F10 to open a command prompt window.
notepadand hit Enter.
- Select File > Open and specify "*.* all files" for the file type option.
- Browse for the REG file you downloaded (tpmbypass.reg), right-click it and select Merge.
- Voila, Windows 11 will be installed.
The contents of the REG file if you are curious.
