Whenever I try to add any site to favourites (by dragging it to favorites bar/Alt-Z/Ctrl+D/clicking in UI) nothing happens.
The Favorites dir in my %userprofile% exists, is writeable, and has items.
Interestingly though the All Users equivalent seems broken:
C:\Users\All Users>mkdir Favorites
A subdirectory or file Favorites already exists.
C:\Users\All Users>cd Favorites
The system cannot find the file specified.
I'm testing with IE 11.0.09600.
I've tried resetting user settings. (inetcpl.cpl -> Advanced -> Reset)
