Hello AskPerf blog, Travis Gradert here from Microsoft Customer Services and Support. I handle quite a number of Powershell cases for our support team, and have noticed that we get a lot of cases where customers are asking for help with things that we do not support. I wanted to write here to help explain what we do and do not handle in our support team when it comes to Powershell. The easy part of this is that we do not support custom or 3rd party scripts. There is no support for the creation of a script. CSS representatives may put in a best effort to you as the customer, however engineers may not have the expertise required.
In the example above, I am trying to update help for the PSReadLine module on my Windows computer. Take a close look at the error message. Notice the spelling of the module name in the message:
Powershell Download Help
DOWNLOAD 🔥 https://urlin.us/2y5GYb 🔥
The Update-Help cmdlet constructs the URL of the CAB file containing the updated help. The URL path is case-sensitive. The updated help files use the new name with the capital L. PowerShell 6 and higher is installed side-by-side with Windows PowerShell. When you run Update-Help, the cmdlet attempts to update the help for both versions of PowerShell. The name of the module that Update-Help uses is based on the name of the folder where the help is stored. For Windows PowerShell this is C:\Program Files\WindowsPowerShell\Modules\PSReadline.
The root problem in Windows PowerShell 5.1 is that the module is automatically loaded at startup using the PSReadline name (with the lowercase l). Use the following steps workaround this problem and update the help.
These steps load the module in your session using the proper name, which allows Update-Help to use the correct name to find the help content. You may consider adding the Remove-Module and Import-Module commands to your profile script for Windows PowerShell 5.1.
When you install or update PowerShell version or install a new operating system that comes with the PowerShell installed then you need to make sure to update the help content from Microsoft website and that can be done using Update-Help command and that is recommended once in a month because some help contents get outdated and MS continuously updates their help content.
where ever I am directly doing in powershell. That is working fine. But, when I store "C:\Program Files\Splunk\bin\splunk" cmd btool props list --debug in test.ps1 and running the script from powersell then, I am getting the error.
I have seen that it was possible to set winhttp proxy with netsh to solve the problem, but powershell update-help clearly don't use winhttp proxy, tested it on my desktop and it just use the proxy set-up in ie.
There are scripts out there that get around this by finding each module's helpURI, downloads the package (using a regular webclient object) and then runs update-help specifying the already downloaded help file.
We don't have an authenticating proxy but I had a similar problem with update-help. It seems our gateway may be set up not to allow requests from powershell, but does allow requests from IE. In our case running fiddler allowed the request from powershell to get through the gateway\proxy. Not sure how, maybe fiddler changes the user-agent string or something, but might be worth a pop if your network is set up similarly.
BTW if anyone from Microsoft is monitoring, please can you at least make the update-help -verbose option report the URLs it is trying to request as this made troubleshooting impossible. I was using fiddler to try to work out what URLs powershell was trying to request.
This happens because Help is actually a function not an alias (but it has an alias of Man to help out those coming from a Unix background) which allows it to work differently (where as Aliases are just different names for the exact same functionality).
Not exactly sure why but what I can tell you is that I have installed and tested the commands I have on the workflow server and they work as expected. So I don't really need to call these commands to a different machine. I'm just looking for a way to pass a simple Powershell command from workflow using some tokens and get it executed. Can anyone help me? I can create the commands in Workflow easily, I just need a way to execute them from Workflow.
PowerShell scripts are the tool of choice for many admins, but how do you make them easy for others to use? In this article, Greg Moore shows how to add professional looking help to your scripts that work just like the help in cmdlets.
As noted above, the first and most obvious solutions for providing help that come to mind are the ones mentioned at the start of the article. However, like most things, PowerShell provides a better way of handling this.
Hopefully, this article has helped you understand how to switch to better parameters and how to enable your users by adding a real PowerShell help to your scripts. As always, the scripts are available on GitHub.
With any other suitable programming language, you will find some built-in help functionality to guide you through the instructions. It may simply describe what the commands are or could be full of example scenarios to get you up and running in no time.
You can run the help command on almost every PowerShell command, provided that the third-party modules include the help resources. The most common way to use the help command is by calling Get-Help with the name of the command you wish to look up.
Getting the description and syntax is not the only thing you can do with the Get-Help module. PowerShell allows you to pass on some additional help parameters to give you more flexibility on the information you see.
I hope that gives you an idea of how to query and use the PowerShell Get-Help command to look up examples and details of any command. Consider leveraging the help command wherever you get stuck and need to dig deeper to learn more about the modules.
I 'factory reset' my Toolbars and now can see the new 'PowerShell Here' commands in the Tools menu. Nice, thanks.
I could not see how DO sets the Background/Foreground colours for these? The Edit command shows only the CLI DOSPROMPT command with the 'admin' and new 'powershell' options but without the 'color=nn' option?
I can over-ride by adding the 'color' option (and surrounding all the options with quotes as suggested in the CLI link you provided above).
But how does DO set the colours for the DOS Windows?
So the only outstanding issue I can see is that when you try and launch an elevated variant of either ISE or Powershell using CLI DOSPROMPT=powershell,admin or CLI DOSPROMPT=powershellise,admin it will open on the local system path (PS C:\WINDOWS\system32>) all the time if you attempt to launch it from a folder on a UNC path. By comparison, the non-elevated variants detect the UNC path and launch correctly on the UNC path. The elevated variants launch correctly on local paths rather than the system path too (I haven't tested mapped drives as yet).
To help you verify the status of speculative execution side-channel mitigations, we published a PowerShell script (SpeculationControl) that can run on your devices. This article explains how to run the SpeculationControl script and what the output means.
This article provides details about the SpeculationControl PowerShell script that helps determine the state of the mitigations for the listed CVEs that require additional registry settings and, in some cases, firmware updates.

I have tried all of the different methods with still the same outcome. It appears to be doing something, but nothing ever happens. I does not kick off powershell, as I have task manager open and watching to see if powershell actually ever runs.
Hello,
I'm having issues with some powershell commands inside ARS script: I'm experiencing a very weird thing where my code doesn't get executed despite the debug log doesn't shows any error.
I'm attaching both my script and the debug log; i've also semplified the code so that just the essentials commands are left. The script basically does 3 things:
1. creates a local folder on a fixed path on the specified server
2. shares this folder on the root of the server
3. assigns the share to the newly created users.
-----------------------------------------------------------------------------------------------------------------------------
I hope this helps.
