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). The list of the various bug fixes and patches for each of the associated KBs is listed on the Windows 10 Update history support page.
If it's any consolation to 1809 users, it looks like the Cumulative Updates to the older versions of Windows 10 released today all introduce the problem with the Seek Bar in Windows Media Player to Windows 10.
