Introduction: http://blogs.technet.com/b/packagemanagement/archive/2015/04/29/introducing-packagemanagement-in-windows-10.aspx
From the Introduction: PackageManagement is essentially a Package Management Aggregator. It creates a unified and consistent PowerShell interface for users and provides a plug-in model at the back end that different installer technologies or package managers can plug-in as providers, using PackageManagement APIs. Each provider further manages one or multiple package sources (repositories) where software packages are stored.
In PowerShell, install the module:
Get-Command -Module PackageManagement Get-PackageProvider Get-PackageSource
Use these commands to register or unregister
Register-PackageSource
