One more reason to keep your system patched. There is some nasty malware out there that wants your computer.
If you have 'Automatic Updates' enabled your computer will download these updates for you in the background. Then when you shutdown your system these patches will be applied to your system. If you leave your computer on overnight they will automatically be installed and your system will be rebooted if necessary.
Warning: If you leave your computer on at night make sure you save all your work or you run the risk of losing it if your system has to be rebooted.Enabling Automatic Updates
If you don't have 'Automatic Updates' enabled on your computer, I would suggest that you turn it on as soon as possible. If you don't want to enable this feature, you can always update your computer by visiting the Windows Update site and downloading and installing the patches manually.
To enable Automatic Updates (Windows XP):
- From the Start menu, select the Control Panel folder.
- Double-click the System applet in the control panel folder.
- Click the 'Automatic Updates' tab.
- Check the 'Automatic (recommended)' option. (optional: if you don't like this feature, you can set it to: 'download but not install the update', 'just notify you', or 'disable this feature altogether' [not recommended])
- Press the OK button when done.
- From the Start menu, select 'All Programs' then 'Windows Update'
- In the left pane, click the 'Change settings' link.
- Check the 'Install updates automatically (recommended)' option. (optional: if you don't like this feature, you can set it to: 'Download updates but let me choose whether to install them', 'Check for updates but let me choose whether to download and install them', or 'Never check for updates' [not recommended])
- Press the OK button when done.
