Great News! On Tuesday (3/24/09),Microsoft published PowerShell 1.0 on Windows Update!
PowerShell 1.0 through MU is only offered:
· As an optional update
· If you don’t have any other version of PowerShell installed (including V2 CTPs) on your machine
· .NET 2.0 is installed on the machine
· OS is one of: XP-SP3, W2K3-SP2, Vista-RTM, Vista-SP1
With PowerShell 1.0 on Windows update, it will now reach a broader audience, (3.5 million downloads so far). This will help the user community to get ready for the rich set of features of PowerShell V 2.0 on the upcoming release of Windows 7 OS. Also it is safe to assume that the PowerShell 2.0 will be pushed through WU/MU/WSUS for enterprise deployment.
Cheers!
