Microsoft explains that Windows 10 1909 can significantly reduce update downtime

Microsoft recently released the November update for Windows 10 2019 (Version 1909) and will push users through Windows Update, Update Assistant, and Media Creation tools. Note that as a feature update, the 1909 update is only available to users running the Windows 10 May 2019 update (1903), and interested friends can manually check for updates through Windows Update.

During Thursday’s online discussion, Microsoft’s Windows Insider team revealed that the size of the 1909 update package was smaller than any previous version of Windows 10 (the boot package was only 180KB in package size).

When the user launches the Windows 10 November 2019 update, Microsoft installs the 180KB launch package before extending the various branch details.

Depending on the volume structure, the October 2018 update (1809) or previous versions have a volume of around 3.5GB (or even less) for its 1909 update package.

The 2019 May Update (1903) platform with no cumulative updates installed, with its 1909 update package at 330MB or less.

Fully installed with cumulative updates for the May 2019 update (1903) platform, its 1909 update package size is only 180KB.

Version 1903 and 1909 have the same set of system files.

That’s what makes Windows 10 1909 so different, the team says. Unlike earlier Windows 10 feature updates, the 1909 monthly quality update process used new service technologies.

Microsoft includes the 19H2 feature in the 19H1 cumulative update, but is disabled by default until it is unlocked through this 180KB “launch pack”.

For running 19H1 devices, this is expected to significantly reduce downtime for 19H2 updates.

The team said they had long wanted to reduce system downtime at the time of the 19H2 update by sharing cumulative updates with 19H1.

We know it’s possible, but we need to figure out the mechanism for implementation. The challenge is to implement it in a way that both retail and commercial customers are familiar with, and Enablement Package is one such technology.

However, Microsoft faced several challenges when delivering the Windows 10 19H2 update, such as build number issues. One employee said it took nearly five months to weigh the design, plan, and implement the changes.
