Open file dialog still looks like from previous age

[jareeq]

Few years ago with beta testing send this message about dialog window looking so old.
HERE

Now back with developer 12.0.7.1837 and it still looks same.
Can I reset registry keys responsible for settings of windows?
Still using windows 7 without aero but guys sitting next to me use it also but Open dialog window looks modern there.
So I thing something stuck in registry we have also old 10.0.5.1710 and this one shows dialog in modern version.

I'm noot sure what could be causing this. I am not aware of any PL/SQL Developer registry keys that could affect this.
