With the impending release of the Windows 11 24H2 update, Microsoft is implementing a significant change that could render super-old PCs obsolete.
The update, set to roll out later this year, will require the POPCNT (Population Count) CPU feature, effectively making it impossible for PCs lacking this capability to run Windows 11.
Mandatory POPCNT Feature in Windows 11
For users who have recently purchased new PCs with modern CPUs, this requirement won’t pose any issues, as most modern processors support POPCNT.
However, individuals still clinging to PCs older than fifteen years will face a stark reality—they won’t be able to boot Windows 11 without POPCNT support.
The decision to mandate POPCNT support stems from the necessity to modernize hardware requirements.
POPCNT, an instruction introduced by Intel with Nehalem-based Core i7 processors in 2008, is now deemed essential for Windows 11 compatibility. Any PCs predating this era will be unable to meet the new standard.
According to insights from Bob Pony’s post on the X platform, Microsoft discreetly made POPCNT a prerequisite for running Windows 11 last year.
This requirement was introduced with Windows 11 Insider Preview build 25905, where various system files, including USB XHCI drivers, began relying on POPCNT instructions for operation.
The discovery has sent ripples across the tech community, highlighting the significance of the POPCNT requirement for Windows 11 24H2. Without POPCNT support, PCs will fail to boot, regardless of any previous workarounds or installation tricks employed by users to run Windows on unsupported hardware.
Windows 11 24H2 Update Boot Block Ahead
While this move may inconvenience users with older PCs, it underscores Microsoft’s commitment to modernizing its operating system and ensuring compatibility with contemporary hardware standards.
As technology evolves, software requirements inevitably shift, necessitating upgrades to hardware infrastructure to maintain optimal performance and security.
As Windows 11 24H2 approaches its release, users with aging PCs may need to consider investing in newer hardware to continue receiving software updates and support from Microsoft.
Alternatively, they may explore alternative operating systems or seek specialized assistance to extend the lifespan of their existing hardware.
Ultimately, the transition to Windows 11 marks a significant step forward in the evolution of Microsoft’s flagship operating system, albeit one that may leave some users behind.
