Patching windows for sql server

Hello,

I was verifying the number of windows updates I needed to run against the current non production and production environments for our database servers hosting SQL Server.

I see important updates and optional updates but no critical updates. I am interested in critical and important updates only and would install only those whenever I am patching database servers. Is there a way to determine which of the available important updates are really required and which I can ignore? Or is it a better practice to patch all important updates too?

Thanks
