I just Installed Windows XP in 10 minutes. It takes that installed XP 10 seconds to boot. Oh and about 5 seconds to shutdown. This XP is special, i can mess about with it, play with the registry, fill it with applications - to test, break it and fix it, break it some more and you name it IT can do it.
..And then at the click of a button i can restore it's state to how it was EXACTLY as it was when XP was first installed.
I'm not talking about system restore or imagaing software. I'm not using sophisticated hardware, warp drive technology or using any magic what-so-ever.
I using an application to do all of this. It costs about £125 and was downloaded.
