Using Powershell to find unsecured accounts with no passwords

Since it's inclusion in Windows Server 2008 I've been tinkering a lot with Windows Powershell.  I rapidly growing to be a convert.  Sorry cmd.exe

Anyway, one of the features is that you can use PS to call WMI.  Which got me thinking on how to solve a problem I had not so long ago; How to identify whether client machines had previously created accounts with no passwords set.

Here is the short script I wrote to do this.

$machine = "localhost"

foreach ($i in $machine)

{Write-Host "Connecting to" $i "please wait..";

Get-WmiObject -computername $i -class win32_UserAccount |

Select-Object Name, Disabled, PassswordRequired, SID, SIDType |

Where-Object ($_.PasswordRequired -eq 0) |

Sort-Object - property name | Write-Host}

Of course I've left out one vital piece which will prevent you from running this script.  This piece you'll have to figure out for yourself.  Hint: Execution Policy

Which leads me to the next question:  How much should one disclose when talking about security?  Would you have put the final piece up to enable this script to be run?
