Introduction
In a recent development, Microsoft is considering preventing the next major Windows 11 update, known as 24H2, from running on very old computers. This potential change arises from a newly discovered requirement for the POPCNT instruction, which many older CPUs do not support.
Understanding POPCNT Instruction
The POPCNT instruction, utilized to count the number of set bits in a value, has been a fundamental part of CPUs for decades. Initially introduced by Intel with its Nehalem architecture in 2008 and by AMD with its Barcelona architecture in 2007, it holds significant applications in cryptography and computational tasks.
Impact on Older CPUs
For users with computers employing CPUs manufactured before the introduction of POPCNT in 2007-2008, there lies a possibility of compatibility issues with future Windows 11 updates. This development particularly affects individuals who have bypassed Windows 11 hardware restrictions on older systems, potentially leading to complications during the installation of the next major update.
Microsoft’s Stance
As Microsoft has been gradually tightening hardware requirements for its operating systems, the restriction on very old CPUs aligns with this trend. However, it remains uncertain whether this change is intentional or an inadvertent consequence of incorporating newer CPU instructions during the development phase.
Relevance to Windows 10
A similar incident occurred previously with Windows 10, resulting in compatibility problems for some older processors. Although Microsoft has not officially commented on the current situation, this highlights the company’s increasing emphasis on stricter hardware requirements.
Considerations for Users
Users with significantly older computers should take into account these upcoming limitations if they intend to continue using Windows 11 in the long term. However, for those who have already ensured compatibility with Windows 11’s hardware requirements, there should be no cause for concern regarding their device’s continued functionality.
Windows 11 update Upcoming Release
Currently, Microsoft is in the final stages of preparing the 24H2 version of Windows 11, expected to be released to manufacturers (RTM) by April. Those eager to explore the upcoming update can opt for the Insider Preview build of Windows 11 version 24H2 (Build 26052) through the Dev or Canary channel.
Conclusion
As technology advances, it’s natural for software companies like Microsoft to evolve their operating systems to leverage newer capabilities. While this potential restriction may inconvenience some users with older hardware, it reflects Microsoft’s commitment to ensuring optimal performance and security for its users.
