How to bypass windows 11 system requirements during installation on an old Laptop?
Apparently, the CPU and RAM don't meet the Windows 11 system requirements. The CPU should be Intel 8th Gen and RAM should be 8GB or more.
One of the easier methods to install Windows 11 on unsupported hardware is to modify the Windows Registry during the installation process. This method involves creating a Windows 11 installation media, booting from it, and then making a registry change before the compatibility check.1. Go to the official Microsoft website to download the Windows 11 ISO file.
2. Use tools like Windows Media Creation Tool to create a bootable Windows 11 USB drive from the ISO file.
3. Boot your PC from the USB drive and start the Windows 11 installation process. Follow the prompts until you reach the screen where it says your PC can't run Windows 11.
4. Press Shift + F10. This key combination opens a Command Prompt window during the installation process.
5. In the Command Prompt, type regedit and press Enter to open the Registry Editor. Now, navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
6. Right-click on the Setup key, select New > Key, and name it LabConfig. Inside the LabConfig key, create new DWORD (32-bit) Value entries with the following names and values:
BypassTPMCheck and set its value to 1.
BypassSecureBootCheck and set its value to 1.
Create BypassCPUCheck and set its value to 1.7. Close Registry Editor and the Command Prompt, then continue with the installation process. The setup should now bypass Windows 11 system requirements.
major concerns are the following:
- Microsoft may not automatically upgrade your version in annual releases
- The device will be very slow and CPU load very high, as it needs to emulate security related tasks that depend on virtualization
- older drivers especially Intel HD graphics do not support Core Isolation
I have stopped using these "tricks" for these reasons, as the performance was greatly reduced. Thus the reasons why the system requirements are not arbitrary, even though the communication about the "why" could have been better. There is lot of rumour about these requirements, still.
Sure thing everyone should use fTPM (in CPU) instead of TPM chips (outside CPU on mainboard).
