Windows Updates

Microsoft Windows is under constant scrutiny and attack from virus writers, hackers and others with a variety of malicious intents. Security holes are found in Windows with unfortunate regularity but are normally patched within a short period of time. Patches are downloaded and installed automatically through the Windows Update tool which should be activated on your machine. If you're not running Windows Update to get the patches for those holes, your computer is at a high risk for being taken over.

To manually run Windows Update, select one of the following menu paths:

Either:  Start > Windows Update
Or:  Start > Programs > Accessories > System Tools > Windows Update

To set Windows Update to run automaticaly:

1. Select: Start [> Settings] > Control Panel 
2. Select the Security Center
3. Click on Automatic Updates
4. Read through the options and set how you would like Windows to run updates.
5. When finished, click OK.
