disponibile da ottobre powershell V4 … se non erro anche per win7 SP1
Microsoft has announced that Windows 2012 R2, System Center 2012 R2 and Windows 8.1 will be on general availability on October 18. The important point being that Windows 2012 R2 & Windows 8.1 bring PowerShell v4
If the pattern of previous releases is followed they will be available earlier through MSDN.
