Upgrade to SW 2017 SP4

Good day to everyone,

Do you upgrade to Solidworks SP4? I want to know if they are any big problems.

In SP3 I receive often the message that my assembly is corrupt, and it closes when I try to Save as some files.

Recently my Solidworks closed unespectated, when I was trying to modify a component.

Should we consider upgrade the windows too?
