Watching for changes since 26 Sep 2026. Revisions Microsoft made before then were not observed, which does not mean there were none.
Nothing about Windows yet in: roadmap items in progress.
A change belongs to Windows when it comes from a source about the product or one of its names (Windows, Windows 10, Windows 11, Microsoft Windows), when a roadmap entry, Windows release, or known issue lists it, or when an MSRC CVE, CISA entry, or lifecycle date names it. Another product's notes and community posts that only mention Windows are listed under "Also mentioned in" and are not counted as its changes. Sources marked quiet are about Windows alone and have had nothing new for 30 days; check the source before reading silence as "no change".
