The PowerShellGet module is the command (s) for discovering, installing, updating and publishing PowerShell artifacts like Modules, DSC Resources, Role Capabilities, and Scripts.

My co-worker needs to install the Exchange powershell module on his 32 bit Win 7 SP1 workstation, obviously he can't install the EMC. He seems to have hit a road block.

Have older Windows systems on your network? You can give them PowerShell 5's event logging capabilities even if they run Windows 7.
