That's what I thought about, but it's not just one key, its folders as well. And I'm sure there will need to be more in the FileExtension key than just ;shtml. Look...they say to go to: HKEY_CURRENT_USER\Software\Microsoft\DevStudio\6.0\Text Editor\Tabs\Language Settings\HTML
Mine is not even in Microsoft\DevStudio, it's in \Microsoft\VisualStudio. So I went to the 6.0\Text Editor\ folder, but \Tabs does not exist, nor does any other folder with Language Settings. An HTML folder DOES exist however, but there is no FileExtensions key inside it. I could create this key but I'm sure there is more information for the key I would need. Any suggestions?
