Microsoft has provided a number of fixes and updates to several older variants of Windows 10. The October 2018 Update/1809 did not get a new generally-available update today, however.
It’s not Patch Tuesday, but that doesn’t mean Microsoft can’t deliver a boatload of patches for various flavors of Windows 10 via Cumulative Updates (CUs). On November 27, Microsoft made available for download CUs for several of its older variants of Windows 10.
By « older, » I don’t mean ancient. Microsoft rolled out today updates for Windows 10 1803 (the April 2018 Update); Windows 110 1709 (the Fall Creators Update); Windows 10 1703 (the Creators Update); and Windows 10 1607 (the Anniversary Update).
