With the release of Windows 10, we simplified the servicing process by moving to cumulative updates, where each update released contains all the new fixes for that month, as well as all the older fixes from previous months. Today, most organizations deploy these cumulative updates when they are released on the second Tuesday of every month, also called “Update Tuesday.” Because these updates contain new security fixes, they are considered “Security Updates” in Windows Server Update Services (WSUS) and System Center Configuration Manager.
Based on feedback from customers, we are making some adjustments to the updates that we are releasing for Windows 10, version 1703 (also known as the “Creators Update”). With these changes, we will routinely offer one (or sometimes more than one) additional update each month. These additional cumulative updates will contain only new non-security updates, so they will be considered “Updates” in WSUS and Configuration Manager.
