Windows 11 24H2 has received yet another hardware requirement for users with modded Windows 11 installs to watch out for. Bob Pony on X (Twitter) discovered that the SSE 4.2 instruction set is now required to run Windows 11 24H2, starting with build 26080. If the instruction is lacking, the OS won't boot.
If this sounds familiar to you, this new requirement is very similar to the POPCNT instruction requirement that we reported on several months ago. The only difference is that this new instruction set requires the actual SSE 4.2 instruction set. Previously only the POPCNT instruction inside of the SSE 4.2 instruction set was actually required.
