I am trying to run this script in PowerShell. I have saved the below script as ps.ps1
on my desktop.
$query = "SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 2"
Register-WMIEvent -Query $query -Action { invoke-item "C:\Program Files\abc.exe"}
I have made a batch script to run this PowerShell script
@echo off
Powershell.exe set-executionpolicy remotesigned -File C:\Users\SE\Desktop\ps.ps1
pause
But I am getting this error:

pwsh.exe
in your bat file instead of powershell.exe
. Quick explanation: powershell.exe
is v5.1- and pwsh.exe
is 6.0+. More here.
You need the -ExecutionPolicy
parameter:
Powershell.exe -executionpolicy remotesigned -File C:\Users\SE\Desktop\ps.ps1
Otherwise PowerShell considers the arguments a line to execute and while Set-ExecutionPolicy
is a cmdlet, it has no -File
parameter.
I explain both why you would want to call a PowerShell script from a batch file and how to do it in my blog post here.
This is basically what you are looking for:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& 'C:\Users\SE\Desktop\ps.ps1'"
And if you need to run your PowerShell script as an admin, use this:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\Users\SE\Desktop\ps.ps1""' -Verb RunAs}"
Rather than hard-coding the entire path to the PowerShell script though, I recommend placing the batch file and PowerShell script file in the same directory, as my blog post describes.
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass Invoke-WebRequest https://www.example.com/example.ics -OutFile C:\_my\script.ics' -Verb RunAs}";
or powershell -Command "Invoke-WebRequest https://www.example.com/example.ics -OutFile c:\_my\file.ics"
, or using the -File option to same in a .ps1 file, or (New-Object Net.WebClient).DownloadFile
. Any ideas?
If you want to run from the current directory without a fully qualified path, you can use:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& './ps.ps1'"
If you run a batch file calling PowerShell as a administrator, you better run it like this, saving you all the trouble:
powershell.exe -ExecutionPolicy Bypass -Command "Path\xxx.ps1"
It is better to use Bypass
...
Small sample test.cmd

Following this thread:
https://community.idera.com/database-tools/powershell/powertips/b/tips/posts/converting-powershell-to-batch
you can convert any PowerShell script into a batch file easily using this PowerShell function:
function Convert-PowerShellToBatch
{
param
(
[Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
[string]
[Alias("FullName")]
$Path
)
process
{
$encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
$newPath = [Io.Path]::ChangeExtension($Path, ".bat")
"@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
}
}
To convert all PowerShell scripts inside a directory, simply run the following command:
Get-ChildItem -Path <DIR-PATH> -Filter *.ps1 |
Convert-PowerShellToBatch
Where is the path to the desired folder. For instance:
Get-ChildItem -Path "C:\path\to\powershell\scripts" -Filter *.ps1 |
Convert-PowerShellToBatch
To convert a single PowerShell script, simply run this:
Get-ChildItem -Path <FILE-PATH> |
Convert-PowerShellToBatch
Where is the path to the desired file. The converted files are located in the source directory. i.e.,
function Convert-PowerShellToBatch
{
param
(
[Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
[string]
[Alias("FullName")]
$Path
)
process
{
$encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
$newPath = [Io.Path]::ChangeExtension($Path, ".bat")
"@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
}
}
# change <DIR> to the path of the folder in which the desired powershell scripts are.
# the converted files will be created in the destination path location (in <DIR>).
Get-ChildItem -Path <DIR> -Filter *.ps1 |
Convert-PowerShellToBatch
And don't forget, if you wanna convert only one file instead of many, you can replace the following
Get-ChildItem -Path <DIR> -Filter *.ps1 |
Convert-PowerShellToBatch
with this:
Get-ChildItem -Path <FILE-PATH> |
Convert-PowerShellToBatch
as I explained before.
If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted
and then reset with Set-executionpolicy -ExecutionPolicy Default
.
Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.
# Check current setting
Get-ExecutionPolicy
# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com | tee ping__google.com.txt }
# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es
Another easy way to execute a ps script from batch is to simply incorporate it between the ECHO and the Redirection characters,(> and >>), example:
@echo off
set WD=%~dp0
ECHO New-Item -Path . -Name "Test.txt" -ItemType "file" -Value "This is a text string." -Force > "%WD%PSHELLFILE.ps1"
ECHO add-content -path "./Test.txt" -value "`r`nThe End" >> "%WD%PSHELLFILE.ps1"
powershell.exe -ExecutionPolicy Bypass -File "%WD%PSHELLFILE.ps1"
del "%WD%PSHELLFILE.ps1"
Last line deletes the created temp file.
If your PowerShell login script is running after 5 minutes (as mine was) on a 2012 server, there is a GPO setting on a server - 'Configure Login script Delay' the default setting 'not configured' this will leave a 5-minute delay before running the login script.
