First of all, let’s start with a warning that you should pay attention to. Microsoft engineers strictly warn against installing this new version on computers that do not meet the Windows 11 system requirements. As it will invite many system problems, the security support given to such computers will be cut in the future. So keep using Windows 10, which will get support until October 2025.
If you don’t listen to the warnings and say whatever happens, there are Windows 11 installation methods on unsupported computers. There can be many different reasons why your computer is not supported for Windows 11. Download the PC Health Check App from here and see the problem. Then you can try to eliminate this problem by following the methods below.
Methods to install Windows 11 on unsupported computers:
- Enable TPM 2.0 on your computer.
- Enable secure boot.
- Repair UEFI.
- Modify the Windows Registry.
Enable TPM 2.0 on your computer:
Trusted Platform Module, TPM for short; It is one of the system features required for Windows 11. However, it may not be available on every computer, or even if it is, the previous version, TPM 1.2, may be installed. You can find out if TPM is installed on your computer by searching for brand and model.
To enable TPM 2.0, you must open your computer’s UEFI firmware settings. Opening the UEFI firmware settings page also has different methods depending on the brand and model. Manufacturers. They release TPM 2.0 update. So if you can’t install Windows 11 due to TPM problem, you should do some research and activate TPM 2.0.
Enable secure boot:
One reason why the PC Health Check App, which we linked in the Description section, is responding to your computer as not supported is because secure boot is not enabled on your computer. Active secure boot is also one of the required system features for Windows 11.
Secure boot may be turned off to install Linux and other Linux distributions. You can also enable secure boot via the UEFI firmware settings page. After activation, run the PC Health Check App again to check if the problem is resolved.
Do a UEFI repair:
UEFI is a BIOS-like interface with which you can interfere with the computer system. UEFI is required for Windows 11. If your computer has BIOS instead of UEFI, you can download Microsoft MBR2GPT via the link here. By downloading the EXE tool, you can convert your drive to GPT format, that is, you can repair UEFI.
If the only problem you have is UEFI-related, instead of driver updates, completely wipe your system and install Windows 11 with an installation media that you can create via the link here. To learn how to switch to UEFI mode during installation, you should search by the make and model of your computer.
Modify the Windows Registry:
- Step #1: Open the Windows Registry.
- Step #2: Go to HKEY_LOCAL_MACHINESYSTEMSetupMoSetup.
- Step #3: Create a new 32 Bit DWORD.
- Step #4: Save the DWORD name as AllowUpgradesWithUnsupportedTPMOrCPU.
- Step #5: Double click the file and enter its value as 1.
- Step #6: Restart your computer.
- Step #7: You’re done.
If your computer does not support Windows 11 due to insufficient CPU or TPM activation, you need to make a few changes to the Windows Registry. If your computer does not have TPM at all, even this change will not enable you to install Windows 11. You must have at least TPM 1.2 installed on your computer.
If you couldn’t install Windows 11 despite all this:
If you look at the methods we have explained, the main reasons why your computer does not support Windows 11 are lack of TPM, lack of UEFI and CPU problem. It is possible to fix some of the existing problems by applying these methods. However, it is not possible to overcome problems such as no TPM.
Despite everything, it is mentioned that there are ways to somehow install Windows 11 on even the oldest computers. However, if you install Windows 11 on a computer in this state, it will not work. Not only does it not work, it can also cause other problems. Windows 10 is supported until October 25, 2025. Windows 11 isn’t a pretty cool version, so keep enjoying Windows 10.
We answered the question of how to install Windows 11 on computers that do not meet the system requirements and do not support Windows 11, and we talked about some of the methods you can apply.
