3. Update What You Use
Updating things that you use should really be something you shouldn’t have to read about in an article to do but my experience shows that people often forget to or just don’t bother. When one of your programs starts whining about a new version being out, update it. Update your system regularly if you don’t have it automatically done and update your drivers as well. There are certain utilities that can help you know what you need to update but you’ll need to pay for them.
On Windows you’ll just have to use the readily available utilities or download software updates online.
On Linux you can just run “sudo apt-get update”, followed by “sudo apt-get upgrade” to solve that. Modern distributions will remind you for updates automatically and have graphic interface managers.
On OS X you can Update from the Mac App Store or use “Software Update” from the Apple menu.
