Hello everyone, I want to know that how to get rid of the junk files in Windows 7. I am not sure what are the softwares or applications that are compatible with the Windows 7 operating system for optimizing the system. Well, I have done an upgradation to Windows 7 from Windows Vista. It has been almost 2 months after the upgradation is done and it seems that the system is already slow. So, please help me in this situation.
