We have a GPO to block access to the Windows Store so users don't install unauthorized software.
We also don't want users to have to sign up for Microsoft accounts and manually install a few existing Store apps were are going to approve.
The first app we want to approve and install on all Windows 8.1 computers (must be available to every domain user who logs into specific computers) is the Microsoft Lync 2013 Store app.
What are the options available to deploy this app and any future updates for the app to users without granting all these domain users access to the Store and then having each user sign into the Store with a Microsoft account and manually install it themselves?
