Powershell ForEach-Object : Cannot bind parameter

powershell

I am trying to get the owner of a process using this code:

(Get-WmiObject -class win32_process | where{$_.ProcessName -eq 'explorer.exe'}).getowner() | Foreach-Object user | out-string

This works great under Windows 8 but in Windows 7 I get this message:

ForEach-Object : Cannot bind parameter 'Process'. Cannot convert the "user" value of type "System.String" to type "System.Management.Automation.ScriptBlock". At C:\Program Files (x86)\Advanced Monitoring Agent GP\scripts\9660.ps1:1 char: 108 + (Get-WmiObject -class win32_process | where{$_.ProcessName -eq 'explorer.exe' }).getowner() | Foreach-Object <<<< user | out-string + CategoryInfo : InvalidArgument: (:) [ForEach-Object], Parameter BindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.ForEachObjectCommand

Please modify the user iterator and try on both 7 and 8:

(Get-WmiObject -class win32_process | 
    where{$_.ProcessName -eq 'explorer.exe'}).getowner() | 
    Foreach-Object {$_.user } | out-string

Powershell – Kill process, then uninstall application–Can I do this with PowerShell, over 400 computers, from a txt file

While this is technically possible, there's probably a better way to go about it.

And speaking of better ways to go about it, You could do this in a GPO with a few lines of code as a startup or shutdown script, which is how I handle this. With a few more lines of code you could log the results of checking for the presence of this thing and/or uninstalling it, which would undoubtedly be useful in your compliance efforts.

If a GPO-linked startup/shutdown script's not an option for whatever reason, I think I'd use PSExec to kill the process on a list of computers read in from file and then script the uninstall in an appropriate language. Seem to me that this is a lot easier in VB, for example.

a=WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{2318C2B1-4965-11d4-9B18-009027A5CD4F}\UninstallString")

If a<>"" Then

WshShell.Run(a&" /S"),1,True
i=i+1

end if

(Goodbye Google Toolbar, in that example which I wrote or copied a few years back. Copied, probably. I am rather lazy.)

Without debugging the PS script you copied, I'd point out that you might be running a different PS version, different PS modules installed/loaded and/or there might be some dependencies that your XP machines don't have in place that's causing problems.

Windows – power shell error: Cannot bind parameter

It looks like you are using PowerShell Vs.2, that version had no support for the new where syntax.

In version 1 and 2 of PowerShell use:

gci | where {$_.subject -like "UTN"}

You need to put curly brackets around the expression and refer to any properties with the $_. prefix.
