Go to 'Installed Updates' and look for KB3035583 and uninstall it. Then look for 'Available Updates' find KB3035583 again, right click on it and you get the option to 'Hide Update' , then click on 'Hide Update'
There may be a Windows' Pane' icon if so hide that as well.
This is what I have done and I get no prompts to install W10.
If you do decide you want W10 sometime just do the same but click 'Unhide'
