Quickly Install Windows 11 on Unsupported PCs without TPM 2.0 and Secure Boot

Microsoft has announced Windows 11, and to install it on your PC, in BIOS/UEFI, TPM 2.0 and Secure Boot should be physically available. That means if on your PC, BIOS/UEFI does not support the TPM 2.0 module and Secure Boot, you can’t install Windows 11 on your PC. Really so many Windows were unhappy when Microsoft has announced these two features as minimum requirements.

Many Windows users were disappointed that they had to either purchase a new PC or adjust further with Windows 10 operating system only. That means even Windows 10 genuine users can not upgrade from Windows 10 to Windows 11. We have already provided an article to install Windows 11 without TPM 2.0 and Secure Boot, but it basically a long procedure. You need Windows 10 as well as Windows 11 ISO files and then have to replace various Windows 11 ISO files with Windows 10. Further, I notice during the installation of Windows 11 in several windows it was showing Windows 10. I was not really happy, and then further, I started testing for new options. Finally, I got success and decided to write this article.

Finally, I am able to bypass TPM 2.0 and Secure Boot enforcement by Microsoft without the help of Windows 10 ISO. That means you can easily edit your Windows 11 ISO and install or upgrade from Windows 10 to Windows 11. Does not it impressive?

If your Windows PC is older than four years, most probably, you will not find the TPM 2.0 chip and secure boot on UEFI. If a TMP module is found on your PC, it will be TPM 1.2. Suppose you find Secure Boot and TPM 1.2 supported on your PC; still, you will be unable to install Windows 11.

Now, you can overcome these restrictions by just deleting a single file from your Windows 11 ISO file. In this gearupwindows article, we will show the quickest way to install Windows 11 on your PC where TPM 2.0 and Secure Boot are unavailable.
