What works the same as Windows

  • A desktop with My Computer, My Documents and Recycle Bin, and a taskbar with a Start button.
  • Runs programs and drivers made for Windows NT, 2000, XP and Server 2003.
  • Aims at Windows Server 2003 compatibility, with an eye on Vista and later.

What is missing

  • It is alpha software: some things may not work and it can corrupt the data on your disk.
