I wasn't saying it was - just that The Microsoft Way tends not to use 
logs to the extent that *NIXen do. 

I admit its been quite a while since I've used Windows in developer mode, 
but about the only place I can remember seeing good logging was from ODBC, 
and only then if it was configured on. The ODBC log entries weren't 
timestamped, but were pretty good in all other respects.[*]

OTOH every *NIX system I've used produces timestamped logs and has a 
mechanism for changing logfiles and keeping the number kept under 
control. IOW I've never see a log under Windows that let me see what had 
happened at about 02:30:15 last Wednesday but all Unices support that 
sort of thing.
 
Hey, Novice - this example below is a good example of the unexpected 
places where a decent log can come in useful.

[*] I was using the ODBC logs to help me tune one of the more 
incompetently written databases I've seen. No adequate application 
documentation of course! So, I was reduced to exercising every function 
of the application with ODBC logging turned on and then working through 
the log to work out what indexes and table storage strategies were needed 
to make the database perform: AKA doing a traditional access path 
frequency analysis after the app had gone live and promptly slowed to a 
crawl. You really can't expect a join on 25,000 accounts to be fast if 
there are no indexes to support it, though somebody had done exactly 
that. And, of course the problem didn't show up during development, which 
had populated the test database with the traditional handful of accounts: 
when each table occupies no more than one or two disk blocks all queries 
are quick.
