When reviewing the Arrival Date of Microsoft Updates, they seem to only arrive once a month on the second Tuesday or Wednesday of the Month.



All versions of Patch Manager


Microsoft began a normalized process in October of 2003 so that 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 time and the synchronization time of the WSUS server in your environment, you may not see the updates come in 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.
