2. Windows Updates. Patches for your operating system can save you from a lot of stress later.

3. Cleaning cookies/cache in the web browser - saves a lot of headaches when trying to load heavy websites. This should be done often, to maximize the potential of the browser.

4. Disk cleanup/disk defrag/backing up the harddrive - should be done monthly, at minimum - will keep you on top of potential disk errors and save data over time.

5. Being careful with downloading attachments and programs - everything is not good for you! Check a reliable source before downloading. Scan with an antivirus program.

6. Upgrade Software! To ensure a long life for your computer, be sure to upgrade software as free final release updates become available, sometimes it may be worth it to buy an upgrade as well, and download/install patches.
