This short guide will show you how to turn on a feature in both Windows 7 and Ubuntu 12.04 (Precise Pangolin) to automatically download and install critical updates. Normally, both systems will prompt you if there are security updates pending to download and install.

Well, if you want to be proactive and install critical updates for your systems, then you’ll want to enable this feature. Enabling it will better protect your systems and close any vulnerabilities that your systems may have before they’re exploited.

So, without wasting anymore of your time, let’s get going.
