Windows 11 Update May Not Boot on PCs Older Than 2011
- Upcoming Windows 11 24H2 update may not boot on PCs from over a decade ago due to required "POPCNT" CPU instruction
- POPCNT debuted in 2008 and appeared in Intel's 2nd gen Core chips (Sandy Bridge, 2011) and AMD chips of the time
- Systems needing POPCNT won't boot Windows 11 24H2, based on Twitter user's discovery
- Implications are that older PCs simply won't boot the 24H2 update releasing this fall
- Issue reminiscent of original Windows 11 launch compatibility questions, but now the hardware requirement seems clearer
