Microsoft has started rolling out optional updates to the latest versions of Windows 10 as part of its weekly C / D release releases. These updates are preview versions of updates that will eventually roll out to corresponding versions of Windows 10 during the Patch Tuesday update next month. As is always the case, those who choose to install these updates will receive only the additional fixes added to the Patch Tuesday package. However, those who choose to skip today’s update will be offered all of these fixes as one.

Today, Windows 10 versions 2004 and later receive an optional patch KB5005611. These versions include the 2004, 20H2 and 21H1 versions. As usual, the packages that target all these versions are identical, since they are built on the same code base and receive the same updates. The patch increases the build numbers to 19041.1266, 19042.1266, and 19043.1266 for versions 2004, 20H2, and 21H1 respectively. The update should also target users running 21H2 on the Release Preview channel soon, as that version will also be delivered as an enablement package for version 21H1.

As for the patch itself, there are a ton of improvements and bug fixes. Highlights include fixes that address Outlook issues, more fixes for the News and Interests flyout, fixes for faulty clock sync, and much more. Here are the highlights of the fixes made in today’s patch:

  • Updates an issue that causes the system clock to go wrong one hour after a daylight saving time (DST) change.

  • Updates an issue that causes applications, such as Microsoft Outlook, to suddenly stop working during normal use.
