The Microsoft Office Sustained Engineering Team announced an important update schedule change that will take place with all future non-security related Microsoft Office product updates. Instead of having both security and non-security related updates to Office products on the second Tuesday of every month, updates will be released as follows:
“We want to let you know about an important change coming to the release schedule for Office updates so that you can plan accordingly. Until now, both security and non-security updates have been released on the second Tuesday of each month. Starting in April, the non-security updates will be released in Microsoft Update and the Windows Server Update Service (WSUS) on the first Tuesday of the month, which is April 5 in this case. This will include all updates that have the Critical or Definition classification. Updates with the Security classification will continue to release on second Tuesday as usual.”
Starting April 2016, therefore, Microsoft will only push out non-security release updates in Microsoft Update and Windows Server Update Service (WSUS) on the first Tuesday of every month (April 5 for the first roll out). All security-related release updates will continue to be roll out on the second Tuesday of every month.
