I don't think the Microsoft update process is compatible even with 
running Microsoft applications, so I make a practice of shutting cygwin 
down entirely.  I ran the updates, including Office 2003SP2, without 
major incident yesterday, on Win2K, WinXP-32, and WinXP-64, total of 4 
installations, with cygwin installed but shut down.  It did take over an 
hour on the system which is on an ordinary DSL line.  There were plenty 
of pop-ups interspersed on the XP systems, about RealPlayer needing an 
update but the site being down, or CA anti-virus not being in a mode 
acceptable to Microsoft.  As you know, Microsoft is not very sympathetic 
to people who want to avoid down time for applications not purchased 
from them.
