- TPM is a security feature, but did you know that you can install Windows 11 without TPM?
- Modifying your registry is one way to do so, and it's even approved by Microsoft.
- If you’re an advanced user, you can fix this problem by modifying the Windows 11 ISO file.
Windows 11 was recently released, and according to the official hardware requirements, to use it, you’ll need to have a TPM chip.
This requirement has already caused a lot of problems with early adopters, and many have reported TMP 2.0 errors when trying to install Windows 11.
Many users don’t have this feature available, especially on older computers, and they don’t want to upgrade in order to try this OS.
However, there are ways to install Windows 11 without a TPM chip, and in this article, we’re going to show you how to do so on unsupported hardware.
What does TPM do?
TPM stands for Trusted Platform Module, and it’s a small chip on your PC. This leads us to the next question, is TPM on the motherboard or CPU?
There are several versions available, and some are on your motherboard while others are integrated into your processor, as a physical chip, or in form of code that runs in a dedicated environment.
As for practical purposes, TPM is used for file encryption, such as BitLocker for example, bootloader protection, and it can be used to protect your passwords against hackers.
Where can I buy a TPM chip?
If you’re looking to buy a TMP 2.0 chip, you should be able to get it from most major PC hardware retailers.
We expect the demand for TPM chips to go up soon, so you might have to hurry and get your TPM chip before others.
Do keep in mind that many processors have a TPM built-in, so be sure to check if your CPU supports this feature before buying a dedicated chip.
How can I install Windows 11 without a TPM chip?
1. Create a new DWORD
- Press Windows Key + R to open the Run dialog.
- Type regedit and press Enter.
- In the Registry Editor, navigate to the following path:
- Right-click the right pane and expand the New menu. Select DWORD 32-bit Value.
- Enter AllowUpgradesWithUnsupportedTPMOrCPU as the name of the new DWORD.
- Double-click the DWORD that you just created.
- Set the Value data to 1 and click OK to save changes.
2. Modify your registry
- Start Windows 11 installation.
- Follow the installation steps until you reach This PC can’t run Windows 11 screen.
- Press Shift + F10 on your keyboard. That should open Command Prompt.
- When the Command Prompt starts, type regedit.exe, and press Enter.
- Navigate to the following key:
- Right-click Setup, expand the New section, and select Key from the list. Name the new key LabConfig.
- Navigate to the LabConfig key that you just created. Right-click in the right pane, expand the New section, and click on DWORD (32-bit Value).
- Create three DWORDs:
- Double-click the first DWORD you created and set its Value data to 1. Now repeat the same steps for the other DWORD.
- Once you’ve made these changes, exit the Registry Editor, and the installation should continue without any problems.
3. Modify Windows 11 ISO
- Download the Windows 11 ISO from Microsoft’s website.
- Locate Windows 11 ISO and double-click it to mount it on your PC.
- Navigate to the Sources directory and locate install.wim file.
- Copy the install.wim file to easy to access location, for example to the Desktop.
- Press Windows Key + X shortcut and choose Windows PowerShell (Admin).
- Now you need to get the information from the wim file. You can do that with this command, but be sure to adjust the path so it matches the location of the wim file on your PC:
dism /Get-WimInfo /WimFile:C:\Users\WindowsReport\install.wim
- Locate the version of Windows 11 that you want to install and memorize its index number. We used 7 for this example, but you need to use the index number of the version that you want to install.
- Run the following command, but we sure to replace the paths and the index number accordingly:
dism /export-image /SourceImageFile:"C:\Users\WindowsReport\install.wim" /SourceIndex:7 /DestinationImageFile:"C:\Users\WindowsReport\install.esd" /Compress:recovery /CheckIntegrity
- Wait for the process to finish and unmount the W11 ISO file.
Now you just need to modify the Windows 10 ISO file by following these steps:
- Download Windows 10 ISO file.
- Now mount it, and copy all its files to your PC to a folder called Windows 11 ISO on your PC.
- Locate install.wim file that you created in the previous steps.
- Go to the Windows 11 ISO directory. Navigate to the sources folder and paste install.wim inside it.
- When asked to overwrite the files, select Yes.
- Download and install ImgBurn software.
- Start ImgBurn and click on Create image from file.
- Now click the Browse for a folder and select Windows 11 ISO folder that you created.
- Click on Chose file icon.
- Select the save location, name the ISO file and click on Save.
- Click the Build icon.
- When the confirmation dialog appears, click on Yes.
- Wait for the process to finish.
- Download and run Rufus.
- Select your USB flash drive and click the Select button.
- Choose the Windows 11 ISO file that you just created.
- Now click on Start and wait for the process to finish.
- Once the process is finished, use the bootable media that you created to install Windows 11.
By completing the above procedure, you’ll have a Windows 11 ISO ready that won’t check for TPM during the installation.
If this process isn’t working for you, take the appraiserres.dll from the Windows 10 ISO file and replace it in the Windows 11 ISO and that should fix the problems with Trusted Platform Module.
What do I do if the PC Health Check app is bugged?
If the PC Health Check App is crashing, there might be an issue with the installation. You should be able to fix that by starting the installation again.
Alternatively, you can wait for Microsoft to release the updated version of the software. If this app isn’t working, you won’t be able to install Windows 11 on an unsupported PC.
What motherboards are Windows 11 ready?
Most newer motherboards support TPM, so if you’re looking for one having this feature, you should consider these gaming motherboards.
It’s not mandatory to use a gaming motherboard, but since these are high-end models, they have all the latest features.
If you don’t want to buy a gaming motherboard, most newer motherboards have support for TPM, so feel free to pick any model that works for you.
Why should I use TPM?
Windows TPM provides a layer of hardware security to your device, and it can help you protect your login credentials from hackers.
This feature is also used for file encryption, so if you want to ensure that your files are perfectly safe from unauthorized access, you need to use it.
As you can see, it’s possible to install Windows 11 without TPM, but it might require that you modify the registry or modify the ISO file.
If you still plan to disable this feature, we recommend using the method that is approved by Microsoft, since it will cause the least problems to your PC.
