Your choice, but I have had no problems after upgrading 1607 to Creators Update (1703).
Do you have Home or Pro? If it's Pro you can defer features updates - which is what the Creators Update is.
If it's Home, then wushowhide is your only option. My System Two in 'my computers' below is a test machine which has system images for all versions of Windows 10. For the earlier versions like 1511 and 1607 I use wushowhide to keep it on that version, so I am familiar with it's use.
You cannot hide an update until it appears in Windows Update when you check for updates. You cannot hide a features update once it has started downloading, so it is
essential you set a 'metered connection' before you check for updates.
Set Wireless Network as Metered or Non-Metered in Windows 10
Set Ethernet Connection as Metered or Unmetered in Windows 10
When you see the 'Features update to Windows 10, version 1703' appear in windows update, then you can run wushowhide to hide it. Once hidden, you should restart your PC. You can now turn off 'metered connections' if you wish.
Note that when 1703 is declared 'Current Branch for Business' this effectively reissues the features update. If you still want to delay it you will have to hide the reissued update.

Josey Wales - ironically (for a thread about hiding 1703) your screenshot is from 1703 Pro and demonstrates the big improvements to Pro's update options that came in with the Creators Update. :)
