If your PC doesn&t run Streaming Single Instructions Multiple Data (SIMD) Extensions 2, you apparently won&t be getting any more Win7 patches.
At least, that what I infer from some clandestine Knowledge Base documentation changes made in the past few days.
Even though Microsoft says it supporting Win7 until January 14, 2020, if you have an older machine —including any Pentium III— you&ve been blocked, and there nothing you can do about it.
