Uninstaller software explained
When you first purchase a new computer it will feel fast, but as the years pass you may start to notice that it becomes slower and continues to deterate in performance often to the point of it becoming unusable. This is often caused by an increase of redundant data sat within your computer left by past applications.
What many people aren't aware of is the standard uninstall program within Windows (Add/Remove programs) isn't actually that effective and leaves a lot of data behind that it should really remove.
Third party uninstall software removes the unnecessary data using a number of different techniques. The outcome is a clean and fully optimized computer that can continue to run at peak performance.
