On Windows 10, quality updates download and install automatically as soon as they’re ready. On the other hand, feature updates are automatically downloaded only when your Windows 10 version is reaching the end of the support period.
Starting with Windows 10 version 2004, Microsoft says it has overhauled the Windows 10 update system and revoked update deferral feature in the Settings app, which allowed consumers and businesses to defer feature updates for up to 365 days.
How to Block New Versions of Windows 10 from Automatically Installing
The first thing you can do to avoid getting the above update problems and more is to take over the control when your Windows 10 updates. This way you can hold off getting updates the moment Microsoft rolls them out, monitor the news for a bit to see if any major errors crop up, then manually do the update yourself.
Recently, Windows Insiders revealed that an update is coming to Windows 10 (around April 2019) which will allow all Windows users (including Home users) to pause updates by up to seven days. In the meantime, if you’re on Windows 10 Pro, enterprise, Education or S, you can postpone updates by going to Settings -> Update & Security -> Windows Update. Here, select the option ‘Choose when updates are installed’ and pick the number of days you’d like to delay it by.
You can block a feature update for up to 365 days. Taking into consideration that Feature Updates are released every seven months, this should be sufficient.
