Disabling Windows 11 TPM2.0 / Secure Boot: Because the latest Microsoft operating system cannot be installed on older computers due to strict security requirements, there are many descriptions on the Internet about how to create a bootable USB system that allows full installation, whether instead of Windows 10 or even for replacing older systems.
Warning: At your own risk, create and use a bootable Windows 11 system with the Rufus program, bypassing Microsoft requirements! Make a backup from which you can restore the system in the event of an error.
Quick Tip: Windows 11 will not be updated after this installation, as the security requirement required by Microsoft (TPM2.0) will be bypassed. There will be no support for the upgrade, so you'll need to do this again when a newer version is released (enough once a year?).
1.) - Windows 11 feature updates are usually released twice a year and include new features and security updates.
2.) - Quality updates are released more often and include minor fixes, security updates.
The program Rufus.exe has been modified in such a way that the requirements of TPM2.0 in the Windows installation system can be bypassed, so that you can easily test it on any old computer that has been manufactured in the last 10 years (I think that no one is older). Let's begin:
Let's start with the creation of a bootable Windows 11, with the modified version of the Rufus.exe program (version: 3.17 / 1.31 MB), which can be downloaded from the github site (Microsoft owner). Download Rufus.exe 3.17...
The ready-made ISO image file prepared by Windows 11 can be downloaded from the official Microsoft website, but includes TPM2.0 and other minimum hardware requirements, so the downloaded ISO file can only be installed on newer computers. For installation on older machines, a version created with Rufus.exe must be installed. Download Windows 11...
Caution: Scroll the web page to „Download Windows 11 Disk Image (ISO)”.
Connect the prepared USB flash drive (or pendrive) to a free USB port on your computer. Caution: Save all data on the flash drive (or pendrive) if necessary, as all data will be deleted.
Proceed as follows to write with the Rufus.exe program the downloaded ISO file to the connected USB device.
Quick Tip: Rufus is designed to create bootable USB drives for Windows and other systems. The new version 3.16, Beta 2, includes an "extended mode" that allows users to bypass Microsoft's security requirements.
1.) After downloading the Rufus program, just click on the program icon (it can be used without installation).
2.) Immediately automatically detects if a USB drive is already connected and indicates it under the Device entry.
3.) Change the settings in Rufus as shown in the image below:
A.) Select Windows 11 ISO from the boot sector menu. Click the SELECT button.
B.) In the ISO image settings menu, select Advanced Installation. (Extended Windows 11 Installation (no TPM/no Secure Boot/8GB- RAM)).
C.) Choose the modern, end more faster NTFS file system, instead of the default FAT32, under the "File System" entry.
D.) Finally, click the START button. In a few minutes, the program will create a bootable version of Windows 11 that can be installed on older computers.
When finished, a notification will appear in a small window. Click OK, and if you want to install the new Windows 11 immediately, do not disconnect the USB drive, but restart the computer. The installation starts automatically.
