Neptune never made it past beta,but in some ways was ahead of its time. It had a gui that was a little different from 2k,used less resourses(comitt),faster booting(single user machine). It came out prior to 2k(hmmmm how interesting) but was advanced in many ways. I would still be using it but it was very touchy about drivers and installing some programs. MS decided to kill this project Windows 2k Personal Edition (Neptune) to work on Millennium sighs much. And yes I have used Neptune and like many beta it had its faults but it was a good project. Gurgelmeyer I dont know if you still have my email addy but if interested please email me. And yes Neptune was my favorite OS, sighs. I wonder if there is a way to incorporate some of the features of this into 2k? Single user enviorment (faster booting) some gui changes (not xp like) and better memory utilization(less comitt)
