Leave it to the Microsoft marketing department to screw things up. Two reasons (besides customer confusion) renaming Software Update Services (SUS) 2.0 to Windows Update Services (WUS) is a bad move:

  1. SUS 1.0 distributes patches to computers running the Windows 2000, XP, and 2003 OS’s. SUS/WUS 2.0 is supposed to support distributing to other MS applications like SQL Server, Exchange, and Office. Why make the name more specific to “Windows” (the operating system itself) at this point?
  2. SUS (pronounced “suss”) was a unique-enough name. WUS will probably make the Unix guys I work with call me names.

(Note for clarity: Among my many hats at work, I’m one of the SUS administrators.)
