How to install Windows 11 on an old PC without TPM 2.0?

Do you want to install Windows 11 on your old computer that does not have the mandatory TPM 2.0 chip? Here’s how to bypass checking for the presence of the TPM 2.0 security chip and other restrictions (RAM, CPU, etc.), and install Windows 11 using the Rufus software.

The release of the latest version of Microsoft’s operating system, Windows 11, has caused a lot of ink to flow. New hardware components are required in order to install Windows 11. These include the TPM 2.0 security chip. You must also have a relatively recent processor to authorize the installation. You can check the official website of Microsoft to discover the required hardware specifications.

The user is in a way taken hostage if he wants to take advantage of the latest version of Windows, and will necessarily have to change computers! Fortunately, a simple solution exists to circumvent these imposed limitations, and this, as legally as possible, let’s find out together how to do it.

To start, you must first bring a USB key of at least 8 GB which you can buy from Amazon or any merchant, then download windows 11 installer file on the Microsoft website:


Then you must download free software Rufus which you can find on the Rufus official website. The latter makes it easy to create bootable USB keys from ISO, IMG, VHD files, and other known formats.
