Rearrange Apps in iTunes for Windows My iPhone 5c, iOS 10.3.3 used to let me rearrange my apps on my Windows 7 PC through iTunes.
Now I can't seem to be able to get to them on my PC.
This feature has been removed in iTunes 12.7 - but Apple have since released 12.6.3 which retains the feature.
You can install iTunes 12.6.3 on top of / over iTunes 12.7 for any OS that support iTunes 12.7 and both are compatible with iOS 11.

Mac link.
Windows 32 bit link.
Windows 64-bit Link.

If you've already been using 12.7 you may have luck importing your 12.7 lib  to a clean 12.6.3 Library, as outlined on MacRumors, but I had no joy.  

I ended up restoring a backup of my Library [just the catalog not all the tunes] from a time before i updated to 12.7.
