Since I have installed CCleaner on my computer every thing runs slow, real slow. Even after the software is uninstalled the system is still slow and freezes quite often. I have a Dell laptop and scanned my system with their support. They say nothing is wrong but it is still slow. In the year and a half I have had the laptop there has never been a problem until I installed CCleaner. Another issue is when I go to the Windows Add/Remove Programs in the control panel. I continued getting the message "wait while it populates" but the installed programs never populate. None of this happened until I installed CCleaner. What can I do to fix the issues created by CCleaner? How do I reinstall the registry backup files? Maybe if I reinstall that will help my system.
