WMI Scripting Windows 8 error - powershell

Question

I have a problem with WMI in a machine with a Windows 8 Home Edition. I need to catch the CPU usage and the ProcessID by process. I've tried so many ways:
ShellExecute in Delphi
A *.bat with the code
A *.vbs
A *.vbs executed by a *.bat
A *.ps1
A *.ps1 executed by a *.bat
(Maybe some of these ways can be really stupid, but I've tried anyway)
In the User-Click it works perfectally, but by a standalone applicantion it doesn't work.
I have opened the Security on WMIMGMT.msi of some folders and the execution policy (in PowerShell) now is UNRESTRICTED.
This is the code on the *.ps1 file:
$ErrorActionPreference = "SilentlyContinue"
Stop-Transcript | Out-Null
$ErrorActionPreference = "Continue"
$perflist = (get-wmiobject Win32_PerfFormattedData_PerfProc_Process)
foreach ($p in $peflist) {
"" + $p.IDProcess + ";" + $p.PercentProcessTime
}
This is the code on *.bat
powershell -ExcetutionPolicy Unrestricted -File "C:\Somefolder\PP.ps1" > C:\SomeFolder\output.txt
All I got is this output:
get-wmiobject : Invalid query "select * from Win32_Win32_PerfFormattedData_PerfProc_Process"
In C:\Somefolder\PP.ps1:4 character: 14
+ $perflist = (get-wmiobject Win32_PerfFormattedData_PerfProc_Process)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-WmiObject], ManagementException
+ FullyQualifiedErroID : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
Edit1: The code copied as asked:
*.ps1:
$ErrorActionPreference="SilentlyContinue"
Stop-Transcript | out-null
$ErrorActionPreference = "Continue"
$perflist = (get-wmiobject Win32_PerfFormattedData_PerfProc_Process)
foreach ($p in $perflist) {
"" + $p.IDProcess + ";" + $p.PercentProcessorTime
}
*.bat
powershell -executionPolicy unrestricted -file "C:\MonitorPerformance\test.ps1" > C:\MonitorPerformance\output1.txt
Output: (Consulta inválida = Invalid Query; No = in; caractere = character)
get-wmiobject : Consulta inv lida "select * from Win32_PerfFormattedData_PerfProc_Process"
No C:\MonitorPerformance\test.ps1:4 caractere:14
+ $perflist = (get-wmiobject Win32_PerfFormattedData_PerfProc_Process)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-WmiObject], ManagementException

Answer 1

replace this:
$perflist = (get-wmiobject Win32_Win32_PerfFormattedData_PerfProc_Process)
with this:
$perflist = (get-wmiobject Win32_PerfFormattedData_PerfProc_Process)

Answer 2

Windows 8 does not performs WMI actions perfectly when you use x32 applications, I made a dummy x64 application who executes the *.bat and it finally works. Thanks for all the help.
