Occasionally, Windows 10 fails to install updates and instead displays a not very informative error message and an error code such as “0x80060449”. One solution to this problem is to manually stop the update service.

Microsoft changes update model for Windows 10
Due to too many problems, the company may change the concept of updates again; the two big packages will be discontinued and replaced by more small updates.
For internal testers, Microsoft is already testing a new update model, which means that new features in the operating system will no longer arrive in two big phases, spring and autumn, but will arrive as they are released. The idea is certainly better than the current version in that there will be no delays.
