CA PC Tune-Up is no exception. The app has a nice interface and is very easy to use. The program scans 4 main areas - Speed, Stability, Security and Performance. It provides a brief description of its actions as it progresses, and ends by presenting you with a report on its findings. Unsurprisingly, in my experience, you'll have to upgrade to the full version of CA PC Tune-Up in order to actually repair any of the problems found.
So far, CA PC Tune-Up seems like many of its competitors, with a few negative differences. The program was slow and buggy, and has very few configuration options. Installation was slow and required an email address, and the last step of the scanning process - Report - will only let you proceed if you fill in a survey. Luckily for us, there are lots of PC tune-up programs out there, which means that there are plenty of ways to avoid the misfortune of having to use CA PC Tune-Up.
CA PC Tune-Up is an uncomfortable, limited program with overly strict trial limitations.
