Windows 11 24H2 Update, Features, System Requirement and SSE 4.2 Explained

An important information coming out for Windows users - Microsoft is again refining windows 11 with huge update of window 11 24H2. Now, this time window 11 24H2 come with hardware requirement for system that's got the attention of many windows users to SSE 4.2 which stand for streaming SIMD extension 4.2. It means that your system must follow the minimum hardware requirement for using of your system or it will not boot .Is it not headache or concerning for u?

What is SSE 4.2 for Windows 11 24 H2 ?

SSE 4.2 is a an instruction set architecture extension introduced by Intel in 2008 and AMD chip in 2011.it is a part of broader SSE instruction which stand for steaming SIMD extension 4.2 enable window 11 to be more efficient execution of various type of algorithms particularly scientific computing, multimedia application, image processing etc.

What's the system requirement for window 11 24 H2?

Bob Pony on X (Twitter) shows that the SSE 4.2 instruction set must be required to run Windows 11 24H2. If the SSE 4.2 instruction is not compatible with your system hardware, your operating system won't boot.

⚠️ UPDATE: Since Windows 11 Build 26080, a CPU with the SSE4.2 instruction is ALSO REQUIRED TO BOOT Windows 11 Version 24H2!!

Attempting to boot Build 26080+ on systems without the SSE4.2 instruction present will trigger an automatic reboot once it reaches the boot screen phase. https://t.co/iLkYuqQojZ pic.twitter.com/5RCxzoFexQ

It was seen that only the POPCNT instruction set was necessary for booting window 11 but SSE 4.2 instruction set is now required to run Windows 11 24H2 ( for build 26080 or newer). But the CPU release after 2010 has already POPCNT instruction (Population Count)and suitable for SSC 4.2 instruction. It means that the system requirement for windows 11 version of 24H2 will not affect to larger window user. But the much older PCs which is not support the instruction will not boot PCs with windows 11 24H2.

How to check system compatible for windows 11 24H2?

As I said, this changes in window 11 won't be an issues for most of Windows 11 users. Bob Ponys has made a window 11 24H2 tester for verify the windows 11 24H2 with new SSE 4.2 requirement for any window 11 user. However, Any user using window 11 with older processor can check the compatibility by using Bob Ponys tester application as follows:

1. At first, download the window 11 tester application here on to your PC or laptop.

2. After that install the application.

3. Open application and check your system for compatibility with Windows 11 version 24H2.

Conclusion

With the support of SSE 4.2 for window 11 24H2, Microsoft aims to leverage the capability of latest powerful processor to deliver more reliable, efficient and secure computing experience for window user. But, this requirement gives implications for users with older hardware but Microsoft shows the user to meet their requirement with the advancing technology and providing innovation for upcoming future challenges.
