• Office 365 PowerShell Commandlets (cmdlets)
• Microsoft Online Services Sign-In Assistant
• WIndows Azure Active Directory Module for Windows PowerShell  (Renamed from

Note: For Windows 7 and 2008 R2 and higher, PowerShell 2.0 is already installed automatically. Even if the program lists the name as PowerShell 1.0, it is actually 2.0
