How can I install Windows 11 on unsupported cpu?

[Zeltser_Rory]

I recently wanted to upgrade my computer to Windows 11, but found that my CPU does not support it. I tried some methods, but it always felt a bit complicated. Is there a simpler way to install Windows 11 on unsupported  CPU, it seems it does not meet the requirements? Welcome to share your experience, thank you!

By modifying the Windows 11 installer's registry, you can bypass system requirements such as CPU, TPM, and memory:

1. While installing Windows 11, press Shift + F10 to open the command prompt.
2. Type regedit to open the registry editor.
3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
4. Create a new key LabConfig.
5. Under LabConfig, create the following DWORD values:
   BypassTPMCheck: Set to 1
   BypassCPUCheck: Set to 1
   BypassRAMCheck: Set to 1

Close the registry and continue with the installation, then you should be able to install Windows 11 on unsupported CPU hardware.

Windows 11 has strict hardware requirements, and one of the key requirements is support for Secure Boot and TPM 2.0, in addition to a compatible CPU. Specifically, Windows 11 requires an 8th-gen Intel processor or newer, or an AMD Ryzen 2000 series or newer. If your CPU doesn't meet these criteria, it might be considered unsupported. You have to do additional work to install Windows 11 on unsupported CPU.

You can check your CPU’s compatibility with Windows 11 on Microsoft's official website, or by using the PC Health Check tool, which will provide a detailed explanation.

I tried using the Windows Installation Media Creation Tool to modify the ISO file to install Windows 11 on an unsupported CPU. It's a bit complicated, but fun.

1. Using the DISM tool from the command line, you can bypass specific hardware requirements directly during the installation process:
2. Boot with the Windows 10 installation disk and select "Repair your PC".
3. Enter the command prompt and use the DISM command to mount and modify the Windows 11 installation image.
4. Disable TPM, CPU, memory, etc. checks on the image.
5. Then use the modified installation image to install the system.

However, please note that although it can be installed in this way, there may be problems with future updates from Microsoft because these unsupported CPUs no longer receive certain official updates. So this method is only a temporary solution, after all, it is not officially recommended. However, for those who want to experience Windows 11, it is still pretty good.

Some Windows updates, like Windows 24H2, may require newer CPUs that support these instructions. This means it becomes much harder to install Windows 11 on an unsupported CPU.

If your CPU doesn’t support SSE4.1, you might encounter issues running the latest update. If your CPU is older and doesn’t meet these requirements, you could either:

1. Upgrade your hardware (e.g., CPU, motherboard) to something more recent that supports SSE4.1 and Windows 11 requirements.
2. Install an older version of Windows (like Windows 10), which might not have these restrictions.
3. Windows 11 system bypass tool. This kind of apps can help you install Windows 11 on unsupported PC (unsupported CPU processor, No TPM or No Secure Boot.)
