Since Windows 10, windows updates are not generally not supposed to bump the name of the version (ie no Windows 10.1), but revisions DO introduce and alter APIs. These revisions are encoded from the release date.

The current enum-based mechanism does not take this into account and is not suited for the faster release pace, so there is no Qt API to easily differentiate between all the Win10 releases. So far, we had

Version 1507
Version 1511 (November Update)
Version 1607 (Anniversary Update)
Version 1703 (Creators Update)
