What is ISESteroids?

ISESteroids is a PowerShell module designed to specifically extend the built-in ISE PowerShell editor. ISESteroids adds virtually hundreds of sophisticated, efficient and slick features to the ISE editor, and leaves plenty of room for you to customize, configure, and “make it yours”.

Navigation Tools

Because ISESteroids is a module, you simply load that module to add professional editing, refactoring, and security functionality. No installation required, no special privileges needed.

Explore the Features!

To quickly discover what ISESteroids can do for you, take a look at the feature overview with plenty of 5-Minute-Walkthroughs. Or join the fun, and start your ISESteroids trial right now. It’s free, and it takes less that 5 minutes to get it up and running.

Remember, ISESteroids is a module. It’s a simple copy&paste operation. No messy installations. And nothing to clean up if you don’t like it. Simply delete the ISESteroids folder if you want to get rid of it again. Nothing to loose, much to gain.

Free Trial

When you download and install ISESteroids, you have plenty of time to test-drive all of its features. 10 distinct testing days without any feature restrictions get you going. We recommend once you installed ISESteroids, visit the Walkthrough section and enjoy some of the walkthroughs we have prepared for you.

During the trial, you get the chance to experience the difference between ISESteroids Professional and ISESteroids Enterprise. Simply open the menu “Level”, and choose the version you want to test. You can switch anytime, back and forth. Or take a look at the feature section. It tells you exactly what features are exclusive to ISESteroids Enterprise.

Quick Overview

Here is some video footage covering some of the features found in ISESteroids:


Interview with the Maker

ISESteroids is created by PowerShell MVP Dr. Tobias Weltner. He has written many books on PowerShell and is an experienced PowerShell consultant, trainer, and conference speaker.

With ISESteroids, Weltner aims to create your “personal PowerShell consultant”, helping you to learn, master, and leverage PowerShell whenever you code.

Listen to an interview recorded by Microsoft MVP Jeff Wouters at the European PowerShell Summit 2014 in Amsterdam, interviewing Dr. Tobias Weltner (you may want to pay special attention to minute 3 when PowerShell Inventor and master-mind Jeffrey Snover bursts in).


Support and Feedback

ISESteroids is a trademark of Dr. Tobias Weltner

  • Mark Schill

    I don’t see the link to download the preview version.

    • Tobias Weltner

      We added this now, sorry about this. You were a bit too fast for us!

  • Mark Demmer

    Tobias, you convinced me at the PSHSummit, I’m a happy Enterprise user.

    Murphy’s Law: No matter how awesome your script is, someone manages to write a script soooo bad, it breaks yours:

    You cannot call a method on a null-valued expression.
    At C:\SWSetup\Programs\ISESteroids2\Fixer\Command\CommandParameter\CommandParameter.ps1:34 char:13
    + if ($command.Parameters.ContainsKey($ParameterName))

    You cannot call a method on a null-valued expression.
    At C:\SWSetup\Programs\ISESteroids2\Fixer\Command\CommandPositionalParameter\CommandPositionalParameter.ps1:34 char:13
    + if ($command.Parameters.ContainsKey($parameterName) -eq $false)

    Cannot index into a null array.
    At C:\SWSetup\Programs\ISESteroids2\Fixer\Command\CommandPositionalParameter\CommandPositionalParameter.ps1:40 char:9
    + $ParameterObject = $Command.Parameters[$ParameterName]

    Do you need me to mail the script I’m refactor on?

    • Tobias Weltner

      Yes please, at tobias.weltner(AT)email.de!

      In fact, the problem looks worse than it is. You could probably ignore the error messages, and the refactoring result should still be ok. The refactoring scripts may run into AST conditions where information is missing, and then do nothing.

      The fixer in question is “Case-Correct Parameter Names” inside the node “Command”. You can see it when you click the “Advanced” tab in the refactoring addon.
      Either disable this one for now (uncheck the check mark), or right-click it and open it to fix it yourself. The easiest fix would be to put it into a try-catch block to silence the errors.

      I’d still greatly appreciate you sending me the script you refactored, so I can add more logic to the script to not throw the errors in the first place.

      • Problem is fixed now in the latest release.

  • Can we get a link to 2.0 Version History?

  • Herbert Preschern

    Hello Tobias,

    I tried out the ‘Normalize Variables.ps1’ of the Refactoring-Tool.
    Normalizing of line 2 and 3 does not work.
    Line 4 works, but if you press the ‘cancel’-button the ‘N’ of ‘VorName’ will be eaten up.

    1 $Vorname = ‘Tobias’
    2 ${VorName} = ‘Herbert’
    3 “Hello $VorName”
    4 ‘Hello {0}’ -f $VorName

    Great work! I love it!
    Kind regards,

    • What exactly did not work? Can you give an example?
      When you refactor scripts, currently undo history may be broken. This is due to a last minute optimization and will change in the final version.
      Thanks for your feedback…!

      • Herbert Preschern

        Hi Tobias,

        Sorry to be ambiguous. The lines beginning with 1..4 are the example.
        I´ll try another one.

        # Testing Refactoring AddOn: ‘Case-Correct Variable Names’
        # ——————————————————–
        # Made several typos in the variable-name ‘$Name’ and tried to correct them via ‘Case-Correct Variable Names’
        # Further, tried to case-correct the variable-name inside curly-braces and double-quotes.

        # define variable
        ${Name} = ‘Tobias’

        # ‘$Name’ and ${Name} reference the same object
        # (…although, Variable Monitor AddOn shows two separate script variables?!)

        # ‘Case-Correct Variable Names’ inside a double-quoted string
        “Hallo $NAme X${naME}X”


        • Tobias Weltner

          Ah, got it!
          You could do me a great favor: could you post this as a bug to the support system (at the bottom of the isesteroids pages on powertheshell.com)? This would help me a lot in managing these issues.

  • Zdzislaw “Stisse” Twardy

    Hi Tobias

    Please make changes in the GUI (if it is possible)
    1. The row number should use the same font size as script text use (or where I can change it)
    2. It is possible to add the possibility to choose if I will print script with row number or without it


    • Ok, we can add an option for font size. Currently, you can print scripts without line numbers only.
      I’d love you to add both items as separate feedback items into our feedback system (at the bottom of the ISESteroids pages).
      This way, you can track progress, and I won’t forget about them 🙂

  • Greg Steward

    When ever I try to install ISESteroids using start-ISESteroids or import-mocule ISESteroids, I receive an error messagte stating “\Modules\isesteroids\ISESteroids.dll’ or one of its dependencies. Operation
    is not supported. (Exception from HRESULT: 0x80131515)”

    ANy thoughts?
