So this is where the misinformation starts about this topic.
On Windows 10 Pro, without any Group Policy settings, the message in red on the update screen does NOT appear at all. And neither does the note.
*some settings are hidden or managed by your organization
We'll ask you to download updates, except when updates are required to keep Windows running smoothly. In that case, we'll automatically download those updates.
Both the above only appear IF you have set local GP settings. If you choose NOT to use the GP options, you should follow through and set the active hours options, the restart Options and the check on the advanced options.
All of these are greyed out IF you use GP.
There is another setting that should be set even if using GP. It is on the Restart options screen.
We'll show a reminder when we're going to restart. If you want to see more notifications about restarting, turn this on.
Under the Advanced Options you are able to Choose when updates are installed. (The download of updates DOES NOT imply that they will be automatically installed).
This option allows you to defer the installation of updates for periods of up to 365 days for non critical updates and 30 days for quality and security updates.
You can temporarily
Pause updates for 7 seven days should it be necessary.
Then you can choose HOW updates are downloaded/delivered.
This is the crucial step that all should check, because the defaults are not what most persons would want. The default is ON, and the default is updates downloaded on this PC will be shared with PCs on my local network,
and PCs on the Internet
So, if you leave this option ON, then you should at least set it to only share updates with PCs on my local network.
With the above settings:
I am never caught by a update download, nor am I ever surprised by an update installation or a restart. All it now takes is to ensure that you set aside some time every 24 hours when updates can be installed without affecting your work.
