We use SCCM for Windows updates and we'd rather not have the 1703 client warn users that they need updates before we've tested and approved them for deployment. I don't see any Group Policy in the W10 1703 administrative templates to affect this behavior, but I suspect some of it is coming out of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Security Health\Health Advisor\Update Monitor but nothing there to disable it.
Anyone know how to manage Windows Defender Security Center, especially when it comes to Windows updates? Thanks, Russell
