PowerShell v3 everywhere

PowerShell v3 everywhere | I.T. Proctology:
...you can download and install the “Windows Management Framework 3.0” on your boxes that are not Server 2012 or Windows 8. As in the past this is more than just PowerShell, it includes WMI and WinRM compatibility updates.  (just not a big BITS update like v2 did)
...If you run an OS that is older.  I am sorry, MSFT does not look back.  You can be one version old, but XP / 2003 is way out. 

The creator of PowerShell, Jeffrey Snover, is now in charge of Windows Server and System Center (Architecture), so it is likely that there will be even more usage of PowerShell...
