I couldn't find a thread about this application, and wanted to know a few things about it before I install it. Will it make all kinds of changes to my system when I install it, or will it leave everything default, and let me choose what to change? How will this affect non Microsoft applications? Are there any downfalls to running this application? IE mandatory changes to do other changes, say I want to use a skin it comes with but mandatory have to use the classic start menu. Hope that all made since.
