At present, the Windows Store still has the problem of downloading/updating certain stock applications. Specifically, when trying to download some stock application updates, the store will throw the 0x80073CF0 error code. Still not sure what caused the problem, nor was it certain that Microsoft posted a specific date for the patch, but Microsoft was aware of the problem and was working to solve the problem.
In other news, Microsoft recently renamed the Windows Store application on Windows 10 to the Microsoft Store. Now, this change only applies to the beta version of Windows 10. So it is clear that Microsoft may be testing the name change and collect feedback, and then promote it to a wider audience.
