From the myITforum TipLine:
For those computers configured to obtain updates from Windows Update, when the upgrade to Windows 10 Creators Update is available a notice will appear. For those organizations that want a bit more control over when then PCs get upgraded, it might help to keep this notice from appearing.
To do that, make a slight registry modification. Create the following key and data value…
Registry path: HKLM\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings\
Value name (Reg_dword): Name:HideMCTLink
A data value of 1 disables the notification.
A data value of 0 enables the notification.
