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

Answer 2

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

Answer 3

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 4

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
