How can I tell if my computer is up to date?

Your computer is up to date when you've installed the latest updates for Windows and your programs. To check for Windows updates, follow these steps:

1.Open Windows Update by clicking the Start button. In the search box, type Update, and then, in the list of results, click Windows Update.

2.In the left pane, click Check for updates, and then wait while Windows looks for the latest updates for your computer.

3.If any updates are found, click Install updates. 

You might see both important and optional updates. If you don't see the Install updates button when there are only optional updates, click Optional updates available, choose the ones you want, and then click OK.
