Hi, I bought new hard drive and installed fresh Windows 10 and then upgrade to 1703 Build.

I want this because a problem with files names.

Where they should be like this (The one with blue color):
Reverting back to a prior build because of the highlighting is not a good idea! In Explorer on 1703, I see thumbnail'd photos and videos exactly as you did in 1507.
