Windows tweakers around the world quickly became fans of TweakUI, the tweaking tool developed by the team behind Windows. Users of Windows 7 were disappointed to find that a version compatible with their operating system was not released, and this is where GIGATweaker comes into play.

This is a tweak tool in the classic sense of the word, making it possible to change a huge number of system settings from a single interface and access settings that would otherwise be hidden. When the program is launched you will be prompted to create a System Restore point so any changes you make can be reversed if necessary.

In addition to a huge number of tweak relating to the look of Windows and the option to place restrictions in place to prevent unwanted changes to your computer, GIGATweak also includes a startup manager that can be used to help boost performance.

Each of the tweak are neatly categorised to make it easy to find what you are looking for. Once tweaks have been put in place, GIGATweak includes the option to restart Explorer so you can see them in effect immediately without the need to restart Windows. With the potential to genuinely improve performance free of charge and customise Windows to your liking, this is a wonderful utility.
