The suite of FixIt maintenance tools are certainly a handy bunch, although perhaps not indispensable. Installation is easy and many will be surprised at the inclusion of a paper manual explaining the various facets of the suite. Users can decide whether to use the included internet security elements too and if they are not opted for the FixIt utilities sit easily alongside any existing internet security programs, although it did not recognise my firewall component and flagged this as an issue.
The PC maintenance tools ferret out all manner of files and issues which slow Windows down, even straight after a fresh install, and even used on the latest version of Windows (7). Once installed the application remains in the background either protecting your Windows from failure or just monitoring for information. There is no perceptible hit on system resources from this monitoring.
The suite includes diagnosis, maintenance, system fixes, optimisation, clean-up and recovery, covering all bases for those who want to keep their PC in tip top condition.
