Powershell 3 on Windows 7: New ADDS cmdlets not available

Hello,

I have installed the MSU file KB2506143 on my Windows 7 x86 client to get Posh v3. $PSVersionTable.PSVersion says I'm running Posh v3.

I am interested in the new ADDS cmdlets around replication, e. g. Get-ADReplicationAttributeMetadata. So I run "import-module ActiveDirectory" but I dont get the new cmdlets. No error like "You need Server 2012 to execute this cmdlet", the new v3-cmdlet Get-ADReplicationAttributeMetadata is simply not available in my Posh shell.

Any ideas what's wrong here?

Thanks
