I have done a lot of Windows Store for Business after the release in December 2015.
The result is that the user can see both the public and private store as shown her:
Some customers ask if it is possible to disable the private store. Here is the solution with Intune as MDM tool for Windows 10 AzureAD joined devices:
Create a Custom Configuration policy
Give the policy a name – Windows 10 Custom Policy – RequirePrivateStoreOnly
Enter a Setting name: RequirePrivateStoreOnly
Settings description: RequirePrivateStoreOnly
Data type : Integer
Value : 1
•0 (default) – Allow both public and Private store.
•1 – Only Private store is enabled.
Click Save policy
Now you are ready to deploy the policy for your users
Assign the policy for the user that need the policy
Logoff and logon again on the PC – now the result is that the user only can the Private Windows Store
