If you thought that by using the conventional installer that Windows has, you had completely uninstalled the programs, you have to know that DO NOT as it always leaves certain files loose, as well as logs on the system that take up space and slow down the system.
The most effective way is to do it with Revo Uninstaller, a 1Mb utility that completely uninstalls all programs by deleting files 'trash' so named because they are no longer useful.
It also has a menu of tools where the system is optimized by showing the programs that start with the computer, it also provides access to Windows utilities that are often difficult to find and, most importantly, the Junk File Cleaner a utility similar to CCleaner.
An interesting feature is the 'Hunter Mode' and the 'Drag and Drop Mode' that allows quick uninstallation through a mobile icon that is placed on the desktop, the remarkable thing about this is that it also offers the following options: Uninstall, stop the automatic start, kill the process, open the containing folder, search Google and show the properties .
