In more reason why Microsoft's requirement for hardware trusted platform modules for its upcoming Windows 11 operating system is arbitrary, the company revealed that it is willing to tweak the hardware TPM system requirements to accommodate platforms from 2017, which include the very first generation of AMD "Zen" (Ryzen 1000 series), and Intel 7th Gen Core "Kaby Lake." In a Windows Insider blog posted dated June 28, Microsoft explained in brief why Windows 11 needs TPM 2.0 hardware, and that the "PC Health Check App," the software tool Microsoft is giving users to check whether their PCs measure up to Windows 11, has been temporarily removed from the website while they work on getting its accuracy right.

"The intention of today's post is to acknowledge and clarify the confusion caused by our PC Health Check tool, share more details as to why we updated the system requirements for Windows 11 and set the path for how we will learn and adjust. Below you will find changes we are making based on that feedback, including ensuring we have the ability for Windows Insiders to install Windows 11 on 7th generation processors to give us more data about performance and security, updating our PC Health check app to provide more clarity, and committing to more technical detail on the principles behind our decisions. With Windows 11, we are focused on increasing security, improving reliability, and ensuring compatibility. This is what drives our decisions.
