Microsoft made it even more confusing by releasing the first Insider preview for Windows 11 earlier today. You don't require a specific CPU or TPM 2.0 chip in order to install the preview, as you might have noticed. The company has written a blog post explaining why it did this. It is a desire by Microsoft to know more about the systems that can run Windows 11.
The company stated that preview builds were provided to various systems as part of the Windows Insider Program. This will allow us to learn more about Windows 11 across different CPU models, and inform any future adjustments to our minimum system requirements.
Microsoft claims its 8th-generation Intel processors and AMD Zen 2 processors are "confident" that they will be compatible with Windows 11. Microsoft intends to closely monitor those who test the OS with systems with 7th-generation Intel or AMD Zen 1 CPUs in order to determine if any of those models meet its standards.
Microsoft also has temporarily stopped offering the PC Health Check. It was the software that caused a lot of confusion over whether certain computers could run Windows 11. Microsoft acknowledged that the app was not ready to provide the accuracy or detail you had expected. Microsoft intends to correct the flaws in the app and release it again later this year ahead of Windows 11's general availability in the fall.
