run powershell command over cmd

Question

I'm trying to run this powershell command over cmd.. it worked when i run it directly from powershell.. but when i try to run if from cmd i get errors

Powershell Command:

(Get-WmiObject -Class Win32_Product -Filter "Name='Symantec Endpoint Protection'" -ComputerName localhost. ).Uninstall()

How I run it (cmd):

powershell.exe -Command (Get-WmiObject -Class Win32_Product -Filter Name='Symantec Endpoint Protection' -ComputerName localhost. ).Uninstall()

Output:

Get-WmiObject : Invalid query "select * from Win32_Product where Name=Symantec

Answer 1

Try this:

powershell.exe -Command "& {(Get-WmiObject -Class Win32_Product -Filter """Name='Symantec Endpoint Protection'""" -ComputerName XOS-MS182. ).Uninstall()}"

Answer 2

Try these. The parentheses mean something special to cmd. The filter would require two sets of quotes. Since the pipe is inside the double quotes, cmd ignores it.

powershell "(Get-WmiObject -Class Win32_Product -ComputerName localhost | where name -eq 'symantec endpoint protection').Uninstall()"

powershell "Get-WmiObject win32_product -cn localhost | ? name -eq 'symantec endpoint protection' | remove-wmiobject"

Answer 3

You don't need to use powershell for this task, from an elevated Windows Command Prompt, (cmd), you could use wmic instead:

WMIC.exe Product Where "Name='Symantec Endpoint Protection'" Call Uninstall

Answer 4

The other answers already answer your question of running powershell over CMD. I'd like to recommend you stop using the Win32_Product wmi class. You can read any of the never ending articles explaining why. As for building commands with arguments, I recommend splatting. As a bonus specifically regarding removing SEP, here is a snippet from a production script used to remove Symantec Endpoint using MSIexec and the guid.

$DateStamp = get-date -Format yyyyMMddTHHmmss
$logFile = '{0}-{1}-{2}.log' -f 'SymantecUninstall',$PC,$DateStamp
$locallog = join-path 'c:\windows\temp' -ChildPath $logFile

$uninstalljobs = Foreach($PC in $SomeList){

    start-job -name $pc -ScriptBlock {
    Param($PC,$locallog)
        $script = {
        Param($locallog)
        $MSIArguments = @(
            "/x"
            ('"{0}"' -f '{A0CFB412-0C01-4D2E-BAC9-3610AD36B4C8}')
            "/qn"
            "/norestart"
            "/L*v"
            $locallog
        )
        
        Start-Process "msiexec.exe" -ArgumentList $MSIArguments -Wait -NoNewWindow
        }
        Invoke-Command -ComputerName $pc -ArgumentList $locallog -ScriptBlock $script
    } -ArgumentList $PC,$locallog

}

Just update the guid to match your product. If you want to pull the uninstall string from the registry and use that, it would also be preferable to Win32_Product.

Here are a couple of ways you can find the uninstallstring.

$script = {
    $ErrorActionPreference = 'stop'
    "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
    "HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | foreach{
        try
        {
            $key = reg query $_ /f "Symantec Endpoint" /s | select -skip 1 -first 1
            $key = $key -replace 'HKEY_LOCAL_MACHINE','HKLM:'
            (Get-ItemProperty $key -Name UninstallString).UninstallString
        }
        catch{}
    }
}
powershell.exe -command $script

or

$script = {
    "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
    "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | foreach{
        Get-childitem $_ |
            Where {($_ | get-itemproperty -Name displayname -ea 0).displayname -like 'Symantec Endpoint*'} |
            Get-ItemPropertyValue -name UninstallString
    }
}
powershell.exe -command $script
