I just did an install of Fritzing on Win10 and the directories are in the expected (mostly) place:
c:\Users\user_name\AppData\Roaming\Fritzing
and (slight change) (edit, slight wrong change, there is a user name
there too Image may be NSFW.
Clik here to view.
):
c:\Users\user_name\documemts\Fritzing
(where documents is My Documents on win7). so there is something odd about your installation I expect. As noted however search is also working for me (indicating it will work on Win10)
