Getting Remote Registry WSUS Config

Friday, September 25th, 2009

Using PowerShell to examine the registry is a simple process but to really get the power from PowerShell you need the data in an object.
Once in the object it is far easier to manipulate the data in a fashion that you are used to in the PowerShell command line.

I used the below PowerShell script to verify the “Automatic Update” configuration on a Windows 2003 Sp2 Server. The servers being analyzed are stored in a .txt file on the C:\ partition.
The path of the input list file is stored in the $File string. This method of using a custom object can be very usefull for non-object based data.

Code:

$WSUSREGALL = @()
[String]$File = "C:\server.txt"
$Servers = Get-Content $File
ForEach($Server In $Servers)
{
$Registry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $Server)
$RegKey0 = $Registry.OpenSubKey("Software\policies\Microsoft\Windows\WindowsUpdate\" )
$RegKey1 = $Registry.OpenSubKey("Software\policies\Microsoft\Windows\WindowsUpdate\AU\")
 
$WSUSREG = New-Object System.Object
$WSUSREG | Add-Member -MemberType NoteProperty -Name "Server" -Value $Server
$WSUSREG | Add-Member -MemberType NoteProperty -Name WUServer -Value $RegKey0.GetValue("WUServer")
$WSUSREG | Add-Member -MemberType NoteProperty -Name WUStatusServer -Value $RegKey0.GetValue("WUStatusServer")
$WSUSREG | Add-Member -MemberType NoteProperty -Name TargetGroupEnabled -Value $RegKey0.GetValue("TargetGroupEnabled")
$WSUSREG | Add-Member -MemberType NoteProperty -Name AcceptTrustedPublisherCerts -Value $RegKey0.GetValue("AcceptTrustedPublisherCerts")
$WSUSREG | Add-Member -MemberType NoteProperty -Name AUOptions -Value $RegKey1.GetValue("AUOptions")
$WSUSREG | Add-Member -MemberType NoteProperty -Name NoAutoUpdate -Value $RegKey1.GetValue("NoAutoUpdate")
$WSUSREG | Add-Member -MemberType NoteProperty -Name NoAUShutdownOption -Value $RegKey1.GetValue("NoAUShutdownOption")
$WSUSREG | Add-Member -MemberType NoteProperty -Name NoAUAsDefaultShutdownOption -Value $RegKey1.GetValue("NoAUAsDefaultShutdownOption")
$WSUSREG | Add-Member -MemberType NoteProperty -Name ScheduledInstallDay -Value $RegKey1.GetValue("ScheduledInstallDay")
$WSUSREG | Add-Member -MemberType NoteProperty -Name ScheduledInstallTime -Value $RegKey1.GetValue("ScheduledInstallTime")
$WSUSREG | Add-Member -MemberType NoteProperty -Name UseWUServer -Value $RegKey1.GetValue("UseWUServer")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RescheduleWaitTimeEnabled -Value $RegKey1.GetValue("RescheduleWaitTimeEnabled")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RescheduleWaitTime -Value $RegKey1.GetValue("RescheduleWaitTime")
$WSUSREG | Add-Member -MemberType NoteProperty -Name NoAutoRebootWithLoggedOnUsers -Value $RegKey1.GetValue("NoAutoRebootWithLoggedOnUsers")
$WSUSREG | Add-Member -MemberType NoteProperty -Name DetectionFrequencyEnabled -Value $RegKey1.GetValue("DetectionFrequencyEnabled")
$WSUSREG | Add-Member -MemberType NoteProperty -Name DetectionFrequency -Value $RegKey1.GetValue("DetectionFrequency")
$WSUSREG | Add-Member -MemberType NoteProperty -Name AutoInstallMinorUpdates -Value $RegKey1.GetValue("AutoInstallMinorUpdates")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RebootWarningTimeoutEnabled -Value $RegKey1.GetValue("RebootWarningTimeoutEnabled")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RebootWarningTimeout -Value $RegKey1.GetValue("RebootWarningTimeout")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RebootRelaunchTimeoutEnabled -Value $RegKey1.GetValue("RebootRelaunchTimeoutEnabled")
$WSUSREG | Add-Member -MemberType NoteProperty -Name RebootRelaunchTimeout -Value $RegKey1.GetValue("RebootRelaunchTimeout")
$WSUSREG | Add-Member -MemberType NoteProperty -Name IncludeRecommendedUpdates -Value $RegKey1.GetValue("IncludeRecommendedUpdates")
$WSUSREG | Add-Member -MemberType NoteProperty -Name AUPowerManagement -Value $RegKey1.GetValue("AUPowerManagement")
$WSUSREGALL += $WSUSREG
}
$WSUSREGALL
$WSUSREGALL | Export-Csv "C:\DataWSUS.csv" -NoTypeInformation

Hope this helps.
