TweakNow PowerPack is a suite of applications that let you improve your system. Applications like these are the doctors of your computer. They carry out the most diverse actions to increase your system's performance. The main star of this application, in my opinion, is the RAM optimizer. Basically, what it does is make sure that your applications always have as much memory as possible. The technical explanation goes outside of the scope of this review, though. But rest assured, it kind of works. Then you have the regular tools. There is a system information application that scans your whole computer and tells you everything about it. This is an extremely great tool for when you need to identify a problem in your system and don't know where to look. Everything is well sorted out, so that you can only look at the information without worrying about anything else. PowerPack also has a nice autorun feature that allows you to customize the actions the system carries out when you insert a new CD. However, this feature has now been added to the newest versions of Windows, so you don't need an extra application to do it. There is also a feature that they call Virtual Desktop, which resembles Spaces, an utility that lets you define several spaces in your desktop, different desktops if you will, and you can customize them. This version presented a few updates, the most noticeable ones are in terms of graphics and scanning speed. This version, however, is no longer available, so you might want to resort to other places to get it. You can get the latest version, 2.1, following the download link.
