Microsoft updates only arrive once a month

Table of contents

Updated: June 21, 2016

Overview

When you review your Microsoft® updates and check the arrival dates, all update arrive once a month on the second Tuesday or Wednesday. 

Environment

All Patch Manager versions

Detail

Microsoft started a normalized process in October 2003 so the majority of Windows® Updates are released to the public (downloadable from Microsoft Update and available to download for WSUS) on the second Tuesday of each month. Occasionally, there will be releases on the fourth Tuesday of a month.

 

Depending on the release and WSUS synchronization time in your environment, you may not see the updates until Wednesday of that week (or later if your WSUS server only synchronizes on a set day of the week or month).

 

This phenomenon is commonly referred to as Patch Tuesday or Update Tuesday.
