Microsoft got it right this time with Windows 2000! If I could give it more than 5 stars I certainly would have done so. It's an eight on a scale of one to five. I have been using W2K for over a month now, and the performance and stability are great. "Plug and play" works even better than the Win9x operating systems, and setup is a breeze if you have a relatively new PC (2-3 years old or newer).Make sure you have a decent amount of memory (I recommend no less than 96 mb, 128 mb or more is even better). Certain drivers have been hard to come by (in particular 3D graphics accelerator card drivers) but that should change now that W2K is offically released. However, most of the drivers you need to get your PC going are included and automatically installed for you during setup.If you are using Win9x or Windows NT, get out there and buy W2K. I don't think you'll be disappointed.
