PowerShell v1.0 is available on Microsoft Update
Microsoft have added PowerShell v1.0 as an optional update that is available through the update mechanisms.
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
Hopefully v2 will be available through the same mechanism.
This will make deployment of PowerShell through out the enterprise a much easier proposition
