DLL Help database
today someone was wondering where this dll came from, and I knew there was a site at Microsoft where you can find information about any (Microsoft) DLL, so I'm posting this here as a reminder for my self, and perhaps anyone who doesn't know about the site

http://support.microsoft.com/dllhelp/

you can enter the DLL name and it will tell you on which packages it was included, etc, so you could find other DLLs that might be related as well and avoid many headaches

I use this utility myself to find any missing references, there's no "it works on my machine" excuse
