If it weren't for the other security restrictions in place, that would really be all it takes to run a PowerShell script from a batch file. So if your PowerShell script is called "MyScript.ps1", you'll want to name your batch file "MyScript.bat" and make sure it's in the same folder. To make this work, the batch file will need to be placed in the same folder as your PowerShell script and have the same file name. So we don't have to re-write the batch file for every script, or every time we move a script around, it's going to make use of a self-referencing variable to build the file path for the PowerShell script.

We showed you how to change this setting in How to Allow the Execution of PowerShell Scripts on Windows 7. The default execution policy, Restricted, prevents all scripts from running, and prevents loading profiles. In some Windows versions, the default doesn't allow script execution at all. The Windows PowerShell execution policy determines whether you can run scripts and load Windows PowerShell profiles and configuration files. PowerShell does not allow external script execution by default.The ExecutionPolicy setting in PowerShell prevents execution of external scripts by default in all versions of Windows.There are ways you can change this behavior, but it's probably not something you want to do on every computer you're carrying your scripts around to - especially if some of those computers aren't your own. This is to prevent accidental execution of malicious scripts by simply double-clicking them. PS1 files to Notepad by default, instead of sending them to the PowerShell command interpreter.
