Users will be able to install Windows 11 on PCs with CPUs that are older than the operating system's official support, but they will not be able to get updates and driver upgrades. It's not clear why this is the case.

Even security updates may not be delivered to consumers who have Windows 11 installed on a computer that Microsoft does not officially support. Additionally, it pertains to feature upgrades as well as driver updates that may or may not be received. Older processors will not be supported at all by Windows Update in the future. Because there will be no official update, installing Windows 11 on an older PC can be accomplished by downloading and installing an ISO file on your own computer.

Due to the fact that Windows 11, in comparison to Windows 10, has relatively high system requirements, the problem arises. In the case of Intel, this applies to an Intel Core 7820HQ, an Intel Core of the eighth generation or newer, and for AMD, it applies to an AMD Zen 2 or newer processor. Additional requirements for the system include 4GB of RAM and 64GB of storage space, as well as a graphics card with DirectX 12 compatibility, as well as UEFI with Secure Boot and TPM 2.0. Windows 11 will be released in the fall of this year.
