Windows XP Service Pack 2 (SP2) added the Security Center, which centralize most security-related functions to one control panel. By default, if it finds a problem it will start nagging you to fix it. For example, if you turned off automatic updates or it doesn't recognize your anti-virus application. Here is how to turn off this feature:

    * Open the Control Panel folder
    * Open the Security Center control panel
    * In the left pane, click the link labeled "Change the way Security Center alerts me"
    * Uncheck the item(s) that it's complaining about (i.e.: firewall, automatic updates, or virus protection)
    * Press the OK button.

When you install a new piece of hardware on your computer, you generally install a device driver that tells the OS how to access the new device. Later, if you remove the hardware from your system, the device drivers will still remain installed. These drivers will continue to be loaded even though they're not being used, and consume system resources.

To find and remove these unnecessary drivers follow the instructions below:

    * From the Start Menu, open the Control Panel folder.
    * Double-click the System control panel.
    * Click the Hardware tab, and press the 'Device Manager' button.
    * In the 'Device Manager' window, from the View menu, select 'Show Hidden Devices'.
  

There are times that you may need to disable a device driver for diagnostic or performance reasons. For example, if you think a device driver is preventing your computer from working properly, you can disable it to see if it fixes the problem. Also, by disabling unused drivers you may help decrease boot time of your computer because it doesn't have to load them.

To disable a device driver, follow the instructions below:

    * From the Start menu, right-click My Computer and select Properties.
    * Click the Hardware tab and press the 'Device Manager' button.
    * Expand the category that contains the device that you want to disable.
    * Right-click on the device and select Disable.

The taskbar by default will generally contain the Start button, the Quick Launch toolbar, and the Notification Area. You can customize the taskbar, with additional toolbars such as the: Address, Windows Media Player, Links, Language Bar, and Desktop.
