I am not using Intel, I am using Lenovo.
This refers to the CPU (Central Processing Unit) and nothing to do with Lenovo (which is a product not the CPU), it may or may not have an Intel CPU. Other CPUs will also support these instruction sets.
If you have a relatively new system then the CPU will almost certainly support SSE2 instruction set, which is relatively old.
My laptop is over 4 years old and that supports it and more recent instruction sets.
