Over 92% of computers are infected with Adware and spyware. Such software is rarely accompanied by uninstall utility and even when it is it almost always leaves broken Windows Registry keys behind it. Even if you have an anti-spyware tool your Windows Registry might be broken – developers of those tools are focused on removing Adware and spyware functionality, not every trace of software itself.
Another category of software that is known to leave bits and pieces behind on uninstallation is games. There are a lot of special installation systems that creates strange files, unique entries in your registry file as well as changes system dll’s to other versions. Once you uninstall the game a lot of the special installation changes it made will be left behind, causing you problems.

By using a PC tune-up utility, your system will be more stable, your software will run quicker, and your operating system will boot faster.
Registry problems can occur for many reasons, including references left behind after uninstallation; incorrect removal of software; missing or corrupt hardware drivers; or orphaned start-up programs.
