3. Unnecessary Startup Programs

Every time, when you turn on your computer, as soon as it starts up, a lot of applications launch on their own. These are the startup applications. Having too many of them is one of the factors that makes your computer slow. Before disabling a Startup application always check its publishers, if the publisher is Microsoft or related to your computer manufacturer, then don’t disable them as your computer will not function properly.


Mac: On the menu bar, Find Go -> Applications->Preferences-> User Groups-> Login Items, you will get the list of unwanted programs. You can uncheck the unwanted applications and stop them from launching on their own.
