12 tips for PC users

I love these How-To articles on PCWorld. These are 12 PC tasks that you should do, but a lot of people don't. General maintenance will help you to get the best experience (and life) from your computer. I'll summarize them in a list here:

1. Clean your computer from dust and crumbs and gross stuff like that
2. Back Up your data
3. Guard against viruses and malware
4. Update Your Software
5. Organize Your Files
6. Remove files/programs that take up space (be careful!)
7. Encrypt
8. Change Passwords
9. Optimize Startup
10. Organize Your Inbox
11. Automate
12. Defragment Regularly
