I was given the task of removing bloatware from a brand-new Acer laptop. My (and the laptop owner's) definition of bloatware includes all pre-installed Apps and the Winstore itself. You may disagree with that, but that's beside the point.
I tried the
remove-appxpackage Powershell command with Winstore's ID and got an error, the important part of which is
This app is part of Windows and cannot be uninstalled on a per-user basis. An administrator can attempt to remove the app from the computer using Turn Windows Features on or off. However, it may not be possible to uninstall the app.
I didn't see any such option in the Windows Features menu. Can the Winstore be removed from Win8.1?
Here's the full error message (for reference):
remove-appxpackage : Deployment failed with HRESULT: 0x80073CFA, Removal failed. Please contact your software vendor.

I am sure you figured this out by now, but seeing as you haven't given this question an check mark for correct answer I am giving you my two cents.
First stop the service named:
This should remove the application, but only once the service is stopped. If you cannot find the service in Services, go find it in the registry. The registry name is: Service Name (registry): WSService
Let me know if this helps you a year and a half later. For future reference all applications running a services most likely need that service stopped before a remove is possible.
You should be able to remove the Winstore in the context of the machine, rather than the user (which is implied by the error message). I have met with success removing Group Policy (which also insists that it is a part of Windows) by using a Task Scheduler task (running as LOCALSYSTEM) to stop the service and then remove it.
Since the Winstore is a Windows Service, this solution should work for you.
