Hi FG,
I clean installed using Official ISO then WU to take the build to 26058.1300 twice. I then run the Store updates, never checked the original version of XboxIdentityProvider but I got the same result that it updated to without having to install older version:
I haven't even got to 26063.1 yet. Two clean installs and I have 2.77GB leftover that cannot be cleaned, see Dev thread.
Regards,
