You need more than automatic updates

Windows' "Automatic updates" only downloads "critical" updates. Windows Update and Microsoft Update, which has MS Office updates too, both have a ton of security patches plus added features you can download. The optional updates and hardware-related updates do not automatically download.

So periodically manually surf to the Update site (Windows Update or Microsoft Update) and check out the other two categories of updates -- "Software Updates [optional]" and "Hardware updates".

Update your PC clock for new DST

Here's an update listed as optional that I'd prefer to be mandatory -- update the system time to reflect the new dates for Daylight Savings Time (Microsoft Knowledgebase article 928388). In case you didn't recall, the U.S. and several other countries have decided to change the start and stop dates for DST.

Since your PC clock has the "old" rule, you really do need this update so that the system can change the time automatically when DST arrives and departs.
