Microsoft has published the minimum hardware requirements for installing the latest Windows 11 OS. The biggest obstacle for older computers is the TPM 2.0 chip. Yes, without TPM 2.0 you will PC/Laptop won’t support windows 11. However, two methods have been surfaced online that will help you to bypass TPM 2.0 and Secure Boot.
Install Windows 11 without TPM 2.0 chip
The minimum hardware requirements for Windows 11 OS have been upgraded from Windows 10. The new operating system can be installed on computers with processors Intel Core or AMD eighth-generation Ryzen 2000 or later. In addition, you must have at least 4 GB of RAM, at least 64GB of storage and a video card with DirectX 12 and WDDM 2.0 support. These specifications are available on the majority of devices sold in the last three years.
However, the most stringent constraints are represented by UEFI Secure Boot and especially TPM 2.0. Without enabling Secure Boot and TPM 2.0 you will see that your hardware is not compatible.
Don’t worry, Windows 11 operating system can also be installed on PCs without UEFI Secure Boot and TPM 2.0 chips (or with features disabled). There are two methods: changing the registry or the ISO image.
Bypass Windows 11 TPM 2.0 via Modification of the registry
- During the installation steps of Windows 11, the minimum hardware requirements are checked. If the requirements are not met, you will see a specific message stating that the PC isn’t compatible.
- At this point, it is necessary to press the key combination Shift + F10 to open the command prompt where you have to type “ regedit.exe ” to start the registry editor.
The new LabConfig key must be created in HKEY_LOCAL_MACHINE \ SYSTEM \ Setup, in which to create the following entries:
- Now save the changes and Windows 11 OS compatibility errors will disappear.
Bypass Windows 11 TPM 2.0 via Changing the ISO image
- In the ISO image of Windows 11, you need to replace the file appraiserres.dll in the folder sources with the analogous version present in the ISO of Windows 10.
- After having recreated the image (example: Rufus tool) it is sufficient to “mount” it in Windows 10 and start the setup.
Note: Above tricks work with the preliminary build of Windows 11 released online. Microsoft may block the trick in upcoming builds or the final one. An official document suggests the possibility of circumventing the TPM 2.0 chip requirement, but only for “special purpose” commercial computers.
