我可以运行“hello world”脚本，但尝试运行这个示例脚本：
C:\Users\thufir\Desktop>
C:\Users\thufir\Desktop>powershell -ExecutionPolicy RemoteSigned
Windows PowerShell

PS C:\Users\thufir\Desktop>
PS C:\Users\thufir\Desktop> type .\stock.ps1
# Working example of how to use PowerShell (version >= 2) to access a web service.
$svc = New-WebServiceProxy –Uri ‘http://www.webservicex.net/stockquote.asmx?WSDL’
$svc | Get-Member # Use Get-Member to discover the interface of a web service.
# Get stock quotes.
$svc.GetQuote(‘BA’) # Boeing
$svc.GetQuote(‘AMZN’) # Amazon
$svc.GetQuote(‘SBUX’) # Starbucks

这是政策问题吗？或者，脚本本身有问题？
还：
PS C:\Users\thufir\Desktop>
PS C:\Users\thufir\Desktop> .\hello.ps1
