PowerShell V2 has been available for all platforms since late October, 2009, so from now on all my scripts will be tested only on V2.
I may post older scripts that work on V1, and in fact my new scripts may as well, but I won’t be testing them unless someone specifically asks for a V1 script.
Download V2 from http://support.microsoft.com/kb/968929
Here are direct links to the Windows Management Framework Core for various platforms:
(Windows Management Framework Core includes WinRM 2.0 and PowerShell 2.0)
For Vista and Server 2008 you can also download BITS 4.0:
”BITS is a service that transfers files between a client and a server. BITS provides a simple way to reliably and politely transfer files over HTTP or HTTPS.”
