Windows generally checks for updates directly in the background, without your having to do anything. Since there are Windows updates nearly every month, it seems perhaps there is a problem with your settings if you haven't received any for nearly a year.

I recommend using the built-in feature or Internet Explorer for updates. Firefox may not support all features of Microsoft's site.

By the way, I'm not sure how you ended up on the Firefox support forum when your browser identifies itself as Google Chrome. Do you want to try Firefox??

Microsoft updates require Win IE to work. Try doing a manual update.
