Avoiding Windows 10 Creator, but not other updates

Solution 1:

You should use the 3rd party tool called Windows Update MiniTool which allows to select which updates can be installed and allows to block updates like you could in former Windows versions.

An alternative to the standard Windows Update What you can do:
• Check for updates
• Download updates
• Installing Updates
• Deleting installed updates
• Hiding unwanted updates
• Get direct links to the *.cab / *.Exe / *.Psf update files • View update history
• Configure Automatic Updates
• This tool is like the external powershell module PSWindowsUpdate, but much more advanced and user-friendly features
• The tool relies and use same WU infrastructure, all downloading are through WU it's not a downloader

Here you can change the checking mode to only notify about updates. Here you can select the Feature Update v1703 and click on hide like any other updates.

(I only have this picture for hiding v1607 on 1511 VM, because I was not offered v1703 but it should be the same for 1703).
