Security patches and updates occur frequently. You should have your (Windows) computer set to update automatically, which will take care of critical updates. You should also manually check for, and install OS updates that are not critical on a routine basis.
Automatic updates are only for critical updates. They do not include security patches, service patches, drivers, or other updates. It is recommended you set up your computer to do critical updates automatically, even though they are also included in the standard Windows Updates. You must perform all updates to secure your system. To set up automatic critical updates:
- Click Start > Control Panel > Security if using Windows Vista or higher
- Assure that the option for automatic updates is turned on.
