Windows 10 November 2019 Update is just 180KB

ComputerWorld reports the package that gets downloaded to your PC for the Windows 10 November 2019 Update (version 1909) is surprisingly small. If you have Windows 10 version 1903 installed, the update weighs in at just 180KB. It's more akin to the service packs that were rolled out for previous versions of Windows, this new update is nearly feature-free. The 180KB package is just the thing that turns on the light switch, according to a Windows Insider team member.

In 1909's case, it was months', not years' worth, of fixes, because Microsoft took May's 1903, collected everything that changed from that point on, then added a handful of new features. Voilà...Windows 10 1909.

The two - 1903 and its rehash successor 1909 - are, Microsoft said, identical with the exception of those few new features baked into the latter. "Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files," is how Microsoft put it. The cumulative update for 1903 released Nov. 12, in fact, was identical to the delivered-same-day Windows 10 1909.
