October 20, 2021, Posted by Admin to Windows Installation USB Creator

Microsoft officially released Windows 11 on October 5, 2021, and later announced the latest Windows 11 system requirements. According to Windows 11 system requirements, the computer to be upgraded must support TPM 2.0 and secure boot. We know that legacy BIOS computers do not have TPM 2.0 and secure boot support at all, and even some UEFI computers do not contain TPM 2.0, so for such a demanding system upgrade requirements, some organizations estimates that nearly two-thirds of computers will not be able to upgrade Windows 11. Although Microsoft promises that Windows 10 users can upgrade to Windows 11 for free, the existence of Windows 11 system requirements will prevent most Windows 10 users from upgrading to Windows 11 for free. These users will either buy a new computer compatible with Windows 11 or use some technical means to bypass the Windows 11 system requirements.

This tutorial will mainly introduce how to use technical means to bypass the Windows 11 system requirements to help users install Windows 11 on a legacy BIOS computer. Generally speaking, to bypass the Windows 11 system requirements, we can press SHIFT + F10 to open CMD.EXE when installing Windows 11, then open REGEDIT.EXE in CMD.EXE, create the "LabConfig" registry key under "HKEY_LOCAL_MACHINE\SYSTEM\Setup", and then create registry values such as "BypassTPMCheck" and "BypassSecureBootCheck under" the LabConfig key, and set these registry values to 1.
