The first post-July 29 updates include little documentation, but know that one of them clocks in at more than 300MB

Microsoft rolls out first official Windows 10 patches: KB 3081424, KB 3081427

Microsoft is rolling out a cumulative update for Windows 10, identified as KB 3081424, which replaces the earlier cumulative update KB 3074683, which, in turn, fixed a Windows Explorer crash caused by KB 3074681. To install KB 3081424, you must already have KB 3074683 on your machine. This should be a given, since updates are forced onto Win10 Home and Win10 Pro machines that aren’t attached to an update server.

As best I can tell, this is the first post-July 29 cumulative update for Windows 10. It’s huge, with many hundreds of changed files in the manifest.

The entire description says:

This update includes non–security-related changes to enhance the functionality of Windows 10 through new features and improvements.

Windows 10 updates are cumulative. Therefore, this package contains all previously-released fixes (see KB 3074683). If you have installed previous updates, only the new fixes that are contained in this package will be downloaded and installed to your computer.

The other update, KB 3081427, is an odd bird, called a “Compatibility update for upgrading to Windows 10” and/or “Dynamic Update for Windows 10.” There’s an enlightening description:

Updates in the Windows 10 Dynamic Update category are used by Windows 10 to obtain critical driver, component, and setup improvements during the initial setup.

Yesterday, more updates were pushed for the Windows 10 nagware patches, KB 2952664 and KB 2976978. Presumably those help identify more systems that are ready to run the Windows 10 upgrade, WUX.

It’ll be interesting to see if there are any problems with the whopper patch KB 3081424 and, if so, how quickly Microsoft fixes them.

Stay tuned.
