The overall feeling after testing XdN Tweaker! is disappointment. As a "tweaker", I expected to have more options –and also more interesting ones- to customize my operating system, and not just being able to remove context menu commands or disable Outlook Express's splash screen.
In spite of the fact that I found most of the included tweaks in XdN Tweaker! not really that useful, there are some interesting ones, like the possibility of adding new commands to context menus or the very necessary file association management that enables you to control which program opens what.
On the upside, XdN Tweaker! is very easy to use and includes the option to undo all the changes you make.
