Windows 11 will be installable on PCs with CPUs older than the operating system officially supports, but users may not receive updates and driver updates.
Even security updates may not come in if users have Windows 11 installed on a PC that Microsoft doesn’t officially support. In addition, it concerns feature updates and updates of drivers that may not roll in. Windows Update will not support older processors at all. It is unknown why Microsoft does this.
Installing Windows 11 on an older PC can be done by downloading and installing an ISO file yourself because there will be no official update. The issue arises because, unlike Windows 10, Windows 11 has relatively high system requirements. In Intel, this concerns an Intel Core 7820HQ, Intel Core of eighth-generation or newer, and for AMD Zen 2 or newer.
In addition to a supported 64-bit processor, system requirements are 4GB of RAM, 64GB of storage space, a graphics card with DirectX 12 support, UEFI with Secure Boot, and TPM 2.0. Windows 11 will be released this fall.
