When you uninstall programs from your Windows computer or your Apple computer you want to make sure you have removed ALL traces of the program.
Most people will use the Programs and Features in Windows to uninstall software that they no longer use , however this will leave behind ” residue ” in the computer in the program files and in the registry.
The same applies to the Mac with some of the program being left behind.
That is why I recommend the following programs.
Windows computers – Geek Uninstaller – The Free Edition – this also comes with a force removal which you can use when ” certain ” programs will not uninstall
Mac computers – App Cleaner
