AGP

Windows 11 has elevated system requirements, necessitating four times the memory and storage for AI-driven applications. It can technically run on a minimum of 4GB of memory, but current hardware pricing is challenging due to a silicon shortage affecting various memory types. A retro hardware enthusiast named Omores installed Windows 11 on a DDR1-based system using an ASRock ConRoe865PE motherboard, Intel Core 2 Quad Q6600 processor, 3GB of DDR1 RAM, and an ATI Radeon HD 4650 AGP graphics card. He overcame the lack of AGP support in Windows 11 by using legacy drivers, achieving satisfactory performance for older applications and games. However, Windows 11 version 24H2 requires SSE4.2 CPU instructions, which are not supported by processors from the AGP era, making version 23H2 the last compatible release for such systems.
