Microsoft's 7 Mobile Operating Systems

Adding this all up, Microsoft has several mobile OS products in various stages of production, including

  1. Windows Mobile 6.5
  2. Windows Phone 7
  3. KIN
  4. Windows Embedded Handheld
  5. Windows Embedded Handheld 7
  6. Windows Embedded Standard 7
  7. Windows Embedded Compact 7.
