In Win10 Pro and Enterpise, I think you can still defer updates for up to 365 days, and in Win10 Home you cannot at all.
With all Win10 editions you can hide updates indefinately from Windows Update with the 'Show or Hide Updates Tool' from Micro$oft so that updates do not get installed, as detailed
here in one of my posts.
In a nutshell:
- Grab the Show or Hide Updates Tool from Micro$oft (wushowhide.diagcab).
- Enable 'Metered Connection' in the Properties for your internet connection.
- Run the Show or Hide Updates Tool BEFORE running the normal Windows Update.
- Choose which update(s) to hide from the normal Windows Update.
- Then run the normal Windows Update to get Critical, Security, Driver, and other updates you may need/want.
You can schedule the Show or Hide Updates Tool through Task Scheduler to run on a schedule you want (every day at log on, for example).
You can un-hide hidden updates at any time.
The moment that you disable 'Metered Connection' for your internet connection, Windows Update will resume auto-downloading and updating again.
I like to run the Show or Hide Updates Tool to see what updates are available and would normally be installed by Windows Update, then search to see if people are having issues with a particular update or updates before I go ahead and allow Windows Update to download and install it/them, or if I think I should hide it/them instead.
Just a little FYI here for you that can help you to manage Windows Update.
