Today, Microsoft released a cumulative update for PC users that are on the Windows 10 Anniversary Update, build 14393.1670 (KB4039396). Patch Tuesday, the second Tuesday of the month, is typically when the company offers these updates, but lately it"s been happening twice a month.
But the kicker here is that Anniversary Update users already got a second cumulative update almost two weeks ago, so this is the third. The changelog isn"t nearly as long as build 14393.1613, and it mostly fixes issues that were present in the last update.
Addressed issue where Update History and hidden updates are lost and a full scan for updates happens after installing OS Updates 14393.1532 through 14393.1613, including KB4034658. Installing this update will not restore past update history or hidden updates for users who have already installed the listed updates. However, this current update will address this issue for users who have not yet installed them.
Addressed issue with WSUS update metadata processing that can cause some clients to time out with a 0x8024401c error.
You might recall that the last couple of cumulative updates for the Anniversary Update had known issues where "Update History" doesn"t list previously installed updated, and where hidden updates might be installed. Those were fixed, along with the WSUS known issue.
Interestingly, we still haven"t seen second updates this month for any other versions of Windows 10, and since tomorrow is Tuesday, it seems likely that we may see them then. You can grab today"s update through Windows Update, or you can manually download it here.
