Hi Gang,
I read a Microsoft KB article on mapping .ini files to the registry. This feature of course only works when the only calls made to that .ini file are via Windows API calls. Anyhow it seems as though it's preventing my upgrade from Windows 2003 SP1 to 2003 SP2, because I keep getting a message that it can't update my Win.ini, which is ridiculous . So I would like to remove all .ini mappings that don't come with windows by default. Would a Windows XP PRO (PRO only please) user please post the following key?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping

Thanks a Quadrillion,
Christian Blackburn

heres mine, it's from xp pro w/sp2. hope it helps

Dear Mezron,
Thank you so much for the registry key. Luckily, and logically, I'm on Sp2 as well. That's good news, because I didn't even think about that part .
Cheers,
Christian
