About servicing stack
The servicing stack includes the files and resources that are required to service a Windows image. This includes the Package Manager executable, the required servicing libraries, and other resources. The servicing stack is included in all Windows installations.
Issues that are fixed in thie update
Consider the following scenario:
More than one update is downloaded to a computer, and the installation process is started.
The updates are installed, and the computer waits to be restarted in order to complete the installation process.
The computer shuts down unexpectedly for some reason. For example, the computer crashes.
In this situation, the computer cannot complete the installation process for all the updates by restarting one time. Instead, each update requires a separate restart of the computer in order to complete the installation process.
During the installation of updates, the computer crashes because too many processes use the binary service.
