disable Preview pane for certain file types?

So ya know in Windows Explorer, there's that Preview pane that's really handy for showing a really big version of a jpg thumbnail, right? I find though if I happen to click on an html file - say, to delete it - it takes a while to load the Preview before I can do anything - such as delete it. I would like to know if there is a way to tell Explorer to NOT show a preview for html files only. (The preview is often crap anyway - what's the point?) So yeah. I didn't see any specific settings to pick and choose what gets shown and what doesn't, so maybe you lot have a registry hack for me? Or some other thing that will tweak this otherwise fairly useful feature? Thanks!

I don't believe there is any way to toggle the view on specific files, if there is a registry hack I would be excited to hear about that aswell however!
