I am unsure weather Bart's PE is classified as a Live-CD Toolkit but I have been using it and realy like it. It alows you to build a fully customizeable boot disk that will load a mini XP enviroment with free tools that you compiled into the cd. You can add tools such as spyware scanners, virus scanners, process managers, hijack this, startup managers and such. I Found it very usefull in the past and have just recently started using it again.
