Microsoft to Offer Windows 10 Changelog For Future Updates
10586.104 update released Tuesday is already available.
Microsoft said it's currently delivering Windows updates on two distinct branches: the build 10240 that the company launched Windows 10 with, as well as build 10586, the "Threshold" release that most consumers have migrated to. (Customers who have bought or licensed Enterprise, Business, or Education versions of Windows 10 have the option of remaining on the older build 10240, up to 10 years for some customers.)
