How/where can I check for information about a Security Update? Windows 10

[Taffy087]

I'm having lots and lots of problems at the moment - see my post today in the Bugs & Platform Errors Jan 2020 thread here Performance Issues - Bugs and Platform Errors (January, 2020)

I'm probably clutching at straw straws but I'm desperate to find out if the below emailed Microsoft Security Update Releases message is relevant to my problem.

How/where do I find out please? TIA
