Tuneup Utilities is one of the best software available in the market for the overall improving of performance of your computer. This software takes care of all the possible types of optimizations in your pc so that your pc starts running like a new one.
It has many features which take care of most of the components of the computer. There are links on the left-hand side and their expansions and sub-links on the right hand side.
Customize & is a very good tool to get a complete control over your system and also change the visual styles right from the themes to the boot screens. Various styles and boot screens can be downloaded from their website. Apart from these features there is startup manager which lets you choose which programs need to start at the startup. It also has system information tab which gives you comprehensive information about your system.
The other tabs are Clean up & Repair, Optimize & Improve, Administer & Control, and File recovery & Destruction. These tabs also have related sub-tabs which can be used to further customize your computer and keep it running well all the time.
There have been further versions of Tuneup Utilities in 2008 and 2009 but mostly they have the same features with some additions. I personally feel that every computer should have this software.
