Steps to install Windows 11 ISO “Official insider preview Edition” on a computer with an old processor with no TPM 2.0 chip. About a month ago, a copy of Windows 11 was leaked – and quite surprisingly though it is a preliminary version, it has been overwhelmingly successful among users who have tried it. Then later, specifically on June 24, Microsoft held a special event and officially announced the Windows 11 “Insider Preview” beta OS for developers, and upon the end of the conference, the American giant made it available to all eligible devices that have the minimum specifications to install the new operating system with some Other limitations set by Microsoft are mainly specific to some security and protection additions to the upcoming system.

Update to Windows 11 Preview Version

Among these limitations and requirements to install and run the new Windows on your computer that you can find out with PC Health Check is that its processor is 8th generation or later (for Intel processors) – or 2nd generation or later for AMD processors – with support for a few versions For Qualcomm’s ARM-based versions of Windows tablets, not to mention that you need a new chip called TPM 2.0, which has become a prerequisite in order to be able to upgrade the system, and it is the chip that unfortunately most computers and laptops do not have at the moment, especially the old ones that are 4 years old or older.

In fact, I personally tried this method and these steps in particular and succeeded in installing the latest official beta version of Windows 11 on an old computer with an Intel Core i3-4160T processor and 8GB of RAM (note that you can install on 3 GB RAM). Also, this PC doesn’t have a TPM 2.0 chip in the first place because here what we’ve done is simply trick the system that we’re installing Windows 10 – but the system core is actually the “Install.wim file” that’s Windows 11.
