How can I remove unnecessary programs from my computer?

You can use the built-in tools in your operating system to remove unnecessary programs. For Windows, open the Control Panel and go to Programs and Features where you can uninstall installed applications. On Mac OSX, open the Finder and select Applications from the sidebar, then delete applications that you don’t need. Alternatively, you could use a system cleanup tool such as CCleaner which can help you identify and quickly remove bloatware and unwanted applications.
