What’s Your Candidate For Stupidest Microsoft Bug?

From the “Ripley’s Believe It Or Not” of software bugs: Windows users
who chose a plain desktop background instead of a picture found their
login process taking longer -- instead of getting to their desktop
within a few seconds, it could take up to 30 seconds.

Why? It turned out that the login system was waiting for a
notification that all desktop components had loaded. The desktop
background component sent this notification after loading a picture,
but somehow the code path for a plain background colour forgot this
notification.

These are the sorts of stupidities in Dimdows that are slipping
through QA testing these days.
