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

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   amp   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   amp   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

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  gt    WD PSHELLFILE ps1  ECHO add-content -path    Test txt  -value   r nThe End   gt  gt    WD PSHELLFILE ps1  powershell exe -ExecutionPolicy Bypass -File   WD PSHELLFILE ps1  del   WD PSHELLFILE ps1    Last line deletes the created temp file
