Now, it appears Microsoft may be mandating TPM 2.0, but again, we’re checking on that. Both of these technologies are designed to improve the security of Windows, and prevent malware and ransomware from tampering with encryption keys and other secure elements of the operating system. That earlier page said Windows 11 would also require TPM capable of at least 1.2 support and UEFI Secure Boot. As Microsoft now requires a TPM (Trusted Platform Module), this has led to some additional confusion around hardware support. Many Windows 10 users have been downloading Microsoft’s PC Health App ( available here) to see whether Windows 11 works on their systems, only to find it fails the check. We’ve reached out to Microsoft to clarify its CPU requirements and support, and we’ll update you accordingly. Originally, Microsoft noted that CPU generation requirements are a “soft floor” limit for the Windows 11 installer, which should have allowed some older CPUs to be able to install Windows 11 with a warning, but hours after we published this story, the company updated that page to explicitly require the list of chips above. You can find the full list of supported processors on Microsoft’s site, but here’s the basic breakdown: Windows 11 support for Intel Windows 11 will also only officially support AMD Ryzen 2000 and newer processors, and 2nd Gen or newer EPYC chips.

Older devices that aren’t officially supported will be met with a warning during the Windows 11 install that the upgrade is not recommended, but the OS should still install. That potentially rules out millions of existing Windows 10 devices from upgrading to Windows 11 with full support, and even devices like Microsoft’s own Surface Studio 2 which the company is still selling right now for $3,499. Windows 11 will only officially support 8th Gen and newer Intel Core processors, alongside Apollo Lake and newer Pentium and Celeron processors.


Microsoft has altered its minimum hardware requirements, and it’s the CPU changes that are most surprising here. Windows 11 is arriving later this year as a free upgrade for Windows 10 users, but many are discovering that their hardware isn’t compatible.
