How do I let Microsoft know about a problem I've found in one of their core library routines? Do they have a central repository to report these things?
I am not a member of Microsoft Development Network (MSDN).
Or should I even bother?
I don't know why ChrisN took back his answer. I saw it earlier today when he had it up, He said:
You can report bugs on the Microsoft Connect website (I've done this in the past). You don't have to have an MSDN subscription.
I had not heard of the Microsoft Connect website, but when I used the search box there to search for "Registry Unicode", the first entry listed was a bug very similar to the one I encountered. And clicking through on that entry led me to look at the conversation that appears to be Microsoft people addressing the issue, passing it on to appropriate people and escalating it as necessary.
I have no experience with the Microsoft Connect website, but if it turns out to be as promising as it appears, this may be the answer to my question.
