Unfortunately, your notebook's processor is only supported for SSE 4A and W11 24H2 and 25H2 require a processor that supports SSE 4.2.

You're very welcome.

 

I found this article that indicates you can upgrade a PC to W11 25H2 if the processor supports SSE 4A.

Additionally, the CPU must support SSE4.2 (Intel) or SSE4A (AMD).

 

These instruction sets are designed for x86 processors, specifically to enhance their multimedia processing capabilities. They are part of the Streaming SIMD Extensions (SSE) family, which provides instructions for performing operations on multiple data elements simultaneously.

 

If you want to see if it will work watch this video for the easiest way to do an in-place upgrade from W10>W11.
