Microsoft delivers first cumulative Windows 10 update

Microsoft is rolling out what's expected to be the first of a number of cumulative fix/update rollups for Windows 10.

Microsoft is rolling out the first cumulative package of non-security-focused updates and fixes for Windows 10 one week after the company began making available to users the release-to-manufacturing (RTM) version of the operating system.

Referred to by some company watchers as "Service Release 1," the actual update package is officially known as KB3081424. (Thanks to The Verge's Tom Warren for a pointer to the KB.)

There's not a lot of information so far about what's in today's update, which Microsoft is delivering via Windows Update. The KB page says the following:

"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."

Technically, this isn't the first set of updates to Windows 10 RTM. Microsoft applied a few updates to Windows 10 RTM as part of users' initial upgrade process. That's because there were a couple of weeks between the actual RTM of Windows 10 on July 15 and the July 29 kick-off of customer availability of those bits. Microsoft made available a few updates that the company developed during that delta period.

Today's cumulative update is one of a series of regular performance and reliability fixes and updates for Windows 10 that Microsoft is expected to deliver. One of my contacts said Microsoft is planning to deliver more cumulative update rollups possibly on a weekly basis at least for the first month of Windows 10 availability.

I've asked Microsoft for more information as to what's in today's update and whether the company is planning to deliver similar updates weekly. No word back so far.

We do know that Microsoft will be patching and updating Windows 10 on a rolling basis, with various "servicing branches" available to different customer groups as part of its "Windows as a Service" strategy.

Some customers will have the option of postponing updates for a set period of time, while others on the so-called "Current Branch" will be expected to apply all updates once Microsoft pushes them to them via Windows Update.
