Uninstall unused apps
In Windows, go to Control Panel -> Uninstall or Change a Program and click on the “Installed on” column to sort your apps. This will help you see which are the oldest apps you have installed and sort through them, so you can delete what you don’t use constantly.
You can also sort applications by size, so you can clean up space on your PC and maybe even make it run faster. Ah, the benefits of decluttering!
Check your browser plugins
Browser plugins are an insidious security threat. They seem completely harmless, but the truth is that they can hurt both your privacy and your security. So it’s good to keep things under control, especially because cyber criminals use browsers as the main attack tactic.
