How to Protect Your Computer and Data
If you do some regular computer maintenance and check a few settings, your computer will last longer and your data will be protected. The following tips can help you protect your computer and all the data it holds:
Always install the Critical updates listed by Windows Update.
Use System Restore to repair problems caused by damaged settings or software that doesn’t install correctly.
Install a new driver to fix problem parts.
Make weekly system image backups using Windows 7’s backup program (or the backup program associated with the software version you're running).
Make sure Windows 7’s Firewall is turned on. (Click Start→Control PanelSystem and Security →Windows Firewall.)
Unleash a compressed-air blower on your computer’s fan area and vents often to clean vents and prevent overheating.
