With Windows 11 24H2 Microsoft is tightening the screws, leaving even more PCs officially incompatible with the OS. A newly discovered change in hardware requirements reveals that core files now require a new CPU instruction, POPCNT. If your hardware doesn't support it, the OS will not boot, and there is no way to bypass this change.
Microsoft is going to release Windows 11 version 24H2 this fall. The release will immediately cut off a large number of computers from the ability to install it. It's all about the new requirement for the POPCNT instruction.
It is not available in processors released more than 15 years ago. Which, by the way, are not compatible with Windows 11 due to the requirements for a newer processor and the presence of a TPM. However, until now there have been various methods to circumvent these limitations.
The release of Windows 11 version 24H2 will change everything. It will be very difficult to get around the new restriction. The fact is that system files that are actively used when loading the OS are now compiled to require this POPCNT instruction. So it doesn't start without it.
The instruction was introduced in the mid-2000s in AMD processors and the first generation Intel Core. On processors released earlier, 24H2 will not run. It is worth noting that on newer processors, which are nevertheless not officially supported, existing workarounds will continue to work.
The next version of Windows is based on the new "Germanium" platform. Among its innovations will be expanded artificial intelligence capabilities. They will be integrated into more system applications, as well as into Copilot.
