Windows Update keeps Windows 10 updated by downloading and installing the latest updates, drivers, and hotfixes released by Microsoft.
Starting with Windows 10 build 15002, you can temporarily pause updates from being installed for up to 7 days (Insiders) or 35 days (non Insiders). Some updates, like Windows Defender definition updates, will continue to be installed.
Starting with Windows 10 version 1809, you can use a new group policy to remove access to “Pause updates” feature.
This tutorial will show you how to enable or disable access to the Pause updates feature of Windows Update for all users in Windows 10.
