Windows Server 2008 R2 doesn’t just add ADPowershell – it also adds Active Directory Administrative Center (or ADAC), a new GUI tool for AD administrators. Read about it here. What’s more, while you can’t tell just from looking at it, ADAC is implemented entirely over Windows PowerShell 2.0 and ADPowershell! Every read and write to AD goes through ADPowerShell. So, if you were wondering whether Windows PowerShell and ADPowershell are just for scripters -- they aren’t! Windows PowerShell and ADPowerShell provide a powerful and flexible management API for the construction of management applications of any type.
