Windows 11 Update to Exclude Older CPUs Lacking POPCNT Support

Microsoft's new hardware requirement for Windows 11 24H2 aims to ensure compatibility with next-gen AI and security features.

Microsoft's upcoming Windows 11 24H2 update will require CPUs to support the POPCNT instruction, impacting compatibility with older hardware.
The POPCNT (population count) instruction, essential for various modern workloads including AI, was introduced in CPUs in the mid-2000s.
The requirement aims to ensure Windows 11 PCs can support next-gen AI experiences and other performance and security updates.
Retro-computing enthusiasts and users of vintage PCs are most likely to be affected by this change.
Microsoft's focus on AI and performance improvements reflects a broader industry trend towards more capable and secure computing environments.
