The ActiveRoles Management Shell for Active Directory is a set of PowerShell commands (CMDLETs) that can be used for free to perform administrative tasks within Active Directory.
The RTM version has just released (v1.0.6). According to Dmitry Sotnikov (Powershell MVP), this version has one new cmdlet and a few improvements and bug fixes as well as full PowerShell v2 compatibility, and YES it's still free. AWESOME!!!
