P.S. Please take into consideration that PowerShell Remoting should be enabled on all computers where do you want to perform uninistall:

• $Host.Version 3.0 Beta

I simply put the workstation name and run the script. The result is in output window in comma separated view: workstation name, NT user account name, and user’s e-mail address taken from AD.

Get-QADComputer -Name workstation -osname *XP* | sort name | foreach `
    {
    if (Test-Connection $_.name -Quiet)
        {
        $name = $_.name
        $name + ", " + `
        ((Get-WmiObject Win32_ComputerSystem -ComputerName $name -EA Stop).UserName) + ", " + `
        (Get-QADUser (((Get-WmiObject Win32_ComputerSystem -ComputerName $name -EA Stop).UserName)) -EA Stop | foreach {$_.email})
        trap {$name + ", " + "{0}" -f $_.Exception.Message; continue}
        }
    else
        {
        $_.name + ", don't respond"
        }
    }

Get-QADComputer -OSName *XP | foreach `
    {
    if (Test-Connection $_.name -Quiet)
        {
        $name=$_.name;
        (Get-WmiObject win32_printer -ComputerName $name  | where {$_.name -eq "Microsoft XPS Document Writer"}).delete()
        (Get-WmiObject win32_printer -ComputerName $name  | where {$_.name -eq "Microsoft Office Document Image Writer"}).delete()
        }
    }

$path = "c:\oslang.csv"
#deleting old file if exist one
if (Test-Path "$path")
    {
    Remove-Item "$path"
    }
Get-QADComputer | ForEach-Object `
    {
    if (Test-Connection $_.name -count 1 -quiet)
        {
        $pcname=$_.name
#making for current workstation a variable with oscode
        $oscode = Get-WmiObject Win32_OperatingSystem -ComputerName $pcname -ErrorAction continue | foreach {$_.oslanguage}
#making a variable to switch to needed text depending on oscode (decimal language code)
#it can be wided by adding your language code for example from here: http://www.science.co.il/language/Locale-Codes.asp
        $switch = switch ($oscode) `
            {
            1033 {"English"};
            1049 {"Russian"};
            default {"Unknown"}
            }
#core operation for getting oslanguage using above variables
        Get-WmiObject Win32_OperatingSystem -ComputerName $pcname -ErrorAction stop | foreach {$_.csname + ", " + $switch >> $path}
#trapping error code for last operation. on operation before this last one pointed an option  -erroraction continue which means that it's not capturing with trap cmdlet and exclude double writing workstation names with errors to csv file
        trap {$pcname + ", " + "{0}" -f $_.Exception.Message >> $path; continue}
        }
    }

For this I wrote this script.

#getting the needed workstations. in this example all XPs in our domain
Get-QADComputer -OSName "Windows XP Professional" | foreach `
    {
#each of them is testing for ping. if it's pinging the script continue
    if (Test-Connection $_.name -Quiet)
        {
        $name = $_.name
#generates a string in which is workstation name; username; user's email        
        $name + ";" + `
        ((Get-WmiObject Win32_ComputerSystem -ComputerName $name -EA Stop).UserName) + ";" + `
        (Get-QADUser (((Get-WmiObject Win32_ComputerSystem -ComputerName $name -EA Stop).UserName)) -EA Stop | foreach {$_.email})
#this string is for trapping errors generating by last string and output workstation's name; error message
        trap {$name + ";" + "{0}" -f $_.Exception.Message; continue}
        }
    else
        {
#if the workstation do not pinging there are an output string with name;don't respond
        $_.name + ";don't respond"
        }
    }

It’s is possible to add >> c:\file.csv and import this list to excel.

#getting all computers with win2k8, you can use *2003* for win2k3
Get-QADComputer -osName *2008* | foreach `
    {
#if they are pinging     
    if (Test-Connection $_.name -Quiet)
        {
#if there are no problems with wmi access and server's model matching ml150
        if((Get-WmiObject -computername $_.name Win32_Computersystem -ErrorAction silentlycontinue).model -match "ML150")
            {
#assigning to variable name and model of that server
            $wmi = Get-WmiObject -computername $_.name Win32_Computersystem -ErrorAction silentlycontinue | ft name, model -HideTableHeaders
#checking wmi for errors if everithing is ok then output $wmi
            if (-not $wmi)
                {
                write-warning $_.name + ", WMI Error"
                }
            else
                {
                $wmi
                }
            }
        }
#and if server is not pinging, write it on the screen
    else
        {
        $_.name + ", don't respond"
        }
    }

After that you will receive the list without the headers of servers’ names and models with are math ml150 in the model. You can use whatever you like in this statement or just delete this if statement for output all necessary servers and it’ models.

Hi friends and co-powershellers. I’ve decided to start my own blog and post any of my thoughts and investigations in PowerShell.

I want to share with you this script for finding and deleting one of installed windows updates.

Get-QADComputer -OSName *Professional | ForEach-Object {
if (Test-Connection $_.name -count 1 -quiet)
{
$pcname=$_.name
if (Get-WmiObject Win32_QuickFixEngineering -computername $pcname  -Filter “HotFixID=’KB925877′”)
{
$pcname
copy-item C:\WINDOWS\`$NtUninstallKB925877`$\spuninst -Destination  \\$pcname\C`$\WINDOWS\`$NtUninstallKB925877`$\spuninst -Recurse
PSCX\Start-Process  C:\WINDOWS\`$NtUninstallKB925877`$\spuninst\spuninst.exe -ComputerName  $pcname -Arguments “/quiet /passive /f /norestart”
}
}
}

This script was needed for deleting update kb925877 for installing SP3 for Windows XP and deploying PowerShell and WinRM (Management Framework) in our environment.

First line takes all workstations in our environment (with name containing OSes with names *Professional) and for each of them makes a script block

Get-QADComputer -OSName *Professional | ForEach-Object {

Next it’s checking if computer is turned on

if (Test-Connection  $_.name -count 1 -quiet)

and if there are installed this update

if  (Get-WmiObject Win32_QuickFixEngineering -computername $pcname -Filter  "HotFixID='KB925877'")

After passing these statements runs two commands copying files for uninstalling update and runs them on that computer in silent mode.

P.S. I am using:

• $Host.Version 2.0
• Quest.ActiveRoles.ADManagement 1.3.0.1787
• PSCX 1.2.0.0
