Security Via Subtraction

All software has bugs, so the more software you have installed, the more bugs you have. It's not just the bugs in any individual application, but it's also magnified by interactions between some applications. Thankfully, the converse is also true: the less software you have installed, the fewer bugs you have (statistically, anyway). How many apps have you installed because they were free? How many apps came installed with your PC that you never use? How about companion apps for products you no longer own? Or maybe apps you installed years ago that you've forgotten about. You need to review all of your apps and get rid of anything you aren't using. You can always reinstall them later, if necessary. But removing unused apps will also remove any software bugs and vulnerabilities that inevitably come with them. (It's also one less app to gather and sell personal data.)
