Microsoft’s recent release of Insider Build 26052 for Windows 11 on the Dev and Canary channels brought with it a range of new features, such as the highly anticipated “Sudo for Windows” and an improved Registry editor. However, buried within this update lies an important development that could greatly impact users with older processors.
It appears that Microsoft is making a significant change to the CPU instruction set architecture (ISA) support for next-gen Windows 11. Specifically, the company is now requiring the SSE4’s “POPCNT” instruction as a mandatory prerequisite for running Windows 11. This means that systems powered by older chips lacking this instruction will no longer be able to boot into Windows 11 24H2.
While this change may disappoint those with older PCs, it’s worth noting that bypassing system requirements may still be possible on more modern CPUs that are not on the list of supported chips. An unofficial WinPE tool based on build 26052 has already confirmed compatibility with such CPUs.
Interestingly, the subsequent release following the first 24H2 build, numbered 26058, further reinforces the need for POPCNT CPU instruction. When attempting to install this version of Windows 11, users are confronted with a message stating, “This PC’s processor doesn’t support a critical feature (PopCnt).” This error indicates a similarity to past Windows setups that checked for the presence of necessary instructions such as NX bit, PAE, or SSE2.
While workarounds have previously existed for such blocks, it remains unclear whether Microsoft has closed these loopholes with the latest changes. This development may leave systems with processors like the Intel Core 2 Quad, which are perfectly capable of running a basic Windows 11 PC, unsupported and potentially unserviced.
As the landscape of Windows compatibility shifts, alternatives such as Google’s ChromeOS Flex have emerged as potential solutions for those with unsupported PCs. Consequently, Google has recognized this opportunity and actively encourages users to migrate from Windows 10 and 11 to their ChromeOS platform.
With Microsoft’s ongoing efforts to refine Windows 11’s hardware requirements, it’s evident that compatibility is becoming increasingly stringent. This serves as a reminder that as technology progresses, older systems may face limitations in terms of software support.
