There are huge numbers of performance optimization and fix-it tools available for Windows, and many of these utilities are virtually identical to one another. Often, all you have to choose between is whether you are willing to paying for such a tool or whether you prefer your software to be free. As you’ve probably guessed from name, Cloud System Booster’s unique selling point – although the software is actually free – is the fact that it makes use of an online database to ensure that it is able to provide the most up to date fixes and solutions.

The program is divided into four main sections – cleaner, optimizer, repair and application – and it can be used in a simple on-click mode, or you have the option of switching to advanced mode if you would like greater control over the process. Each section if fairly self-explanatory, with the Application section dealing with the cleaning and optimization of individual programs rather than the system as a whole. The cloud-based approach to optimization really comes into its own when dealing with individual programs as it means that the software is able to quickly respond to the latest updates.

As well as being available for on-demand scanning and optimization, Cloud System Booster can also be configured to run on a schedule. This is great if you want to ensure that your computer is always running at peak performance, or if you want to be sure that the cleaning module is protecting your privacy. In tests, the program seems to yield impressive enough results and is easy enough to be used by more novice computer users – there’s also the option of changing the app’s appearance using skins if you’re into such things.

It is hard to criticize the application as it seems to do a good job without the need fir too much user intervention, but the app cleaner probably takes longer to performs its scans than is strictly necessary. This is because the scanner seems to check for the presence of a huge list of installed programs every time it run – you can manually deselect program you do not have installed, but you will need to remember to re-enable the option should you ever decide that you want to install the application in future.
