hover your mouse over the little blue ball. does it say updates are ready to download, or downloaded updates are ready to install? If the former, in internet, go to "tools" then "windows update" and you'll go to microsoft's page where you'll get to choose updates. Question, if you're not on a network, how are viewing your internet and writing this post (that's a smartass way to say that anytime you are on the internet, you're on a network connected to your ISP's servers.)
Read the updates' descriptions fully too. There are some that you think you wouldn't need, but upon closer inspection, you can often find that the fixes are integrated across several applications. Especially any security fixes.
