I saw this...........According to the report, the March 2018 security update for Windows 7 listed a known issue where a “Stop” error will occur on PCs that don’t support Streaming Single Instructions Multiple Data Extensions 2 (SSE2).
Question : Is my i3-3120M supported/okay
Thanks peter
You're okay. The i3-3120M was released in 2012, and supports SSE2, SSE3 and SSE4. Practically all Intel CPUs since the Pentium 4 (release date 2001) support SSE2.
I've heard some people are complaining about Microsoft dropping Windows 7 support for non-SSE2 CPUs ahead of the regularly scheduled 2020 end-of-support date for Win7, but IMHO the complaints are much ado about nothing. If you don't have SSE2, that means you probably have a CPU from the 1990's, and I really can't imagine why anyone would even try to run Windows 7 on a computer made back in the Windows 98 era. This issue has to be affecting only a very, very, very small number of people.
