I was just helping friends with optimizing their PCs and made a "To-do list", so can anyone tell me if I need to add anything else?
CCleaner
CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. This software is a must for Windows.
