Microsoft today silently released a new Windows 10 Update with version KB4033637 for users running Anniversary Update (version 1607). The company has not provided any changelog for the update which generally it does while releasing Patch updates.
Microsoft is yet to provide any information on the update and we expect that the latest update offered could be a security update for Adobe Flash. One of the Reddit user was successful in getting an answer form one of the Microsoft Support Staff. The Support Staff confirmed that the recent update KB4033637 is a security update for Adobe Flash which is aimed at users with version 1607 x64.
We have reached out to Microsoft as to why the company has released the patch to some systems now instead of including it in the August Patch Tuesday update. We are still awaiting answer on the same and will be updating this article once we get more info on the Patch update.
