I have been playing with Micro2003 a cut down slip stream versions of Windows Server 2003. Some points to note;

1. Very much lighter on both CPU usage and Memory, ideal for servers with a specific task in mind, Go1984 for instance was 99% CPU and 600MB RAM now 70% CPU and 270MB RAM.

2. No Internet Explorer and lots of other things missing hehehe

3. No Windows updates so what you get when you set it up is how it stays.

I find it amazing that Microsoft can't leave out Internet Explorer when some hackers with nLite can do so much more. I expect there will be a Micro7 soon.
