OK, I'm not giving up. Open regedit and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.xml\OpenWithList . See what the value is. If it is blank, or associated to office, you could try changing the value to iexplorer.exe . At this point I'm going to suggest you back up the registry 1st.

Edit:
You know, I don't see any mention of you trying to use the Open With context menu? Have you tried right clicking a .xml file, choosing Open With, and choosing IE from the list? Or if it isn't on the list, browse to it, then set it to always open with IE?
