Yes it’s about XP. It’s old, but a lot of people still use it, and sometimes there’s some stuff that’s really deep in there. So, here’s the story.
At work, I had this very annoying default that every explorer window would open to; that is, with the folders view on. And there was no way to change it. Further more, turning off the folders view made any folder open in another window, with folders view on.
So, here’s how, in case you searched for it:
> Explorer Window > Tools > Folder Options
> File Types > Folder > Advanced
And set default to open instead of explore.
Right, not too hard, but definitely awkward place for such a setting.
