Installing Windows 11 Without TPM 2.0

 Hello everyone, friends. Yesterday, I tried to install Windows 11 and at the beginning of the installation I encountered an error saying that Windows 11 cannot be installed on your device.

Later, while researching this problem on the internet, although my device almost fully supported Windows 11 hardware-wise, I could not install it because my BIOS was old and it didn't even have TPM 1.2, let alone TPM 2.0. Through my research, I found many ways to install without TPM; let's review these methods together.

1st Method (Easiest Way) Changing the Registry Settings

We disable TPM by changing the registry settings.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig]
"BypassTPMCheck"=dword:00000001
"BypassSecureBootCheck"=dword:00000001

Using Notepad, save the above code as a ".reg" file and place it inside your prepared Windows 11 installation files.

If you couldn’t manage to prepare the file, you can download it from here.

TPM Bypass -> Media Fire

After this process, the inside of your installation files will look like this

Now, as soon as we start the installation from the USB we prepared, on the pages before the error appears, press "Shift + F10" to open the Windows Command Prompt.

After the command prompt opens, type "notepad.exe" and open Notepad.


Command Prompt notepad.exe

After opening Notepad via the command prompt, now it's time to access the USB and open our file from there.

Notepad Files

In Notepad, go to files and click on open.

Windows 11 notepad All Files

Here, set the "File type" field to "All Files" so we can see the file we put on the USB.

Windows 11 Merge

If you have done everything smoothly up to this point and can see your file, right-click the file and click "Merge".

Warnings

Two warnings will appear in front of you, click "Yes" and "OK" to both.

After these steps, you can install Windows 11 on your device without any problem.

2nd Method Replacing appraiserres.dll

Download the "appraiserres.dll" file from the link below and replace the "appraiserres.dll" in the "Sources > dlmanifes" folder inside your installation USB with it.
