Normally every update to an operating system should ensure better stability and provide bug and error fixes. Unfortunately this does not happen every time and there are many updates Windows 10 as a result of which operating system, application or driver problems occur. An even bigger problem is when Windows Update no longer runs normally and reports error codes that often don't help.
In the latest versions of Windows 10, Microsoft has slightly changed the mechanism of operation of Windows Update and gives users more freedom frequency of updates and separated driver updates and "non-security" by system ones. Thus the user can choose whether or not to install one update for a driver or to return to the previous version, if the new one does not work properly. This setting is called "Optional Updates" and is found in the settings Windows Update. Here find a complete tutorial on "Optional Updates in Windows 10"
