We have repeatedly mentioned that Windows 10 cumulative update is divided into B update, C update, and D update. Type B updates are stable updates in the Microsoft sense, while Type C and D updates are beta updates, and these updates are usually not widely available to users.
In addition to the above types of updates, there is actually another type of update called service stack update. The so-called service stack update is mainly used to update the underlying services of the operating system.
Microsoft uses service stack updates to solve certain problems at the bottom of the system so that users have a higher success rate when installing cumulative updates and reduce the probability of problems.
According to Microsoft’s official recommendation, users should install the service stack update before installing the cumulative update. After installing the service stack update, it will help improve the success rate of the cumulative update.
But for users, especially enterprise users, installing the update itself is very scary, because no one knows what new problems the cumulative update will bring.
Therefore, users are not willing to install updates whether it is a servicing stack update or a cumulative update, and the failure to install the servicing stack update results in a high rate of cumulative update failure.
To solve such problems, Microsoft is currently merging the service stack update with the cumulative update, so that users can install the update smoothly and reduce the probability of installation failure.
Microsoft stated that the cumulative update and servicing stack update will begin to merge from September 2020, which means that the cumulative update actually includes the servicing stack update.
When the system executes the installation, the service stack update will actually be installed first, and the cumulative update part will be installed after the service stack update installation is complete, so the success rate will be high.
Microsoft hopes to solve the problem of installation failures complained by users. Of course, the actual effect may need to wait for the follow-up development.
