Deferring Upgrades Question

In Windows Update > Advanced Options > there used to be an option to "Defer Upgrades" , but it is gone now.
Any idea where it went?


On the option to "Defer Upgrades":

I would rather defer any build upgrade until a time that I can supervise the install, and I don't want any other updates being installed at the same time. So this seems like a good option for me.

My question is: assuming I know (most likely from this forum) that an upgrade is ready, can I just uncheck the defer box when I am ready to install, or will there be some kind of delay in getting it?
(It's that blurb about maybe waiting x months that confuses me)

Well that is really interesting. Because it was there on initial setup. Now it is gone.

I wonder what option I chose?

1. Before Win 10, did you have Win 7 Home or Win 8/8.1( non-pro version ) ?
Win 7 Home

2. Did you at one point install Insider Preview Win 10 Pro ?
Negative

3. Did you then decide to opt out of Insider program and install Win 10 RTM ?
N/A - Negative


I noticed this and other oddities in the two upgrade installs I did this weekend and last.
Advanced features appearing immediately after install and then disappearing sometime afterward.
I was not paying much attention the first time (other than "hey wait a minute" moments. I was paying closer attention this time.

You can block updates in Home with firewall/HOSTS by blocking update servers.
Disabling some services and tasks might do as well, but it is not quite reliable.
Do not forget to subscribe to updates afterwards: Microsoft Security Bulletin

I am using Services to control Updates. Very clunky and inconvenient. But given no control and no choice it is what I have to do.
