    "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.

    Close all powershell.exe processes. Then rename the PSReadline module folder name to PSReadLine.
    Open an powershell.exe session in Administrator privilege.
    Run Remove-Module PSReadLine to remove the auto-loaded PSReadLine module.
    Run Import-Module PSReadLine (use PSReadLine with capital L).
    Then run Update-Help -Module PSReadLine -Force
    These steps load the module in your session using the new name, which allows Update-Help to use the correct name to find the help content."

Hi Harm_Veenstra ,

 

In this location: "C:\Program Files\WindowsPowerShell\Modules\PSReadLine" the folder name is already with Capital Letter "L".

I have run Your recommended steps:

  • "Open an powershell.exe session in Administrator privilege.
  • Run Remove-Module PSReadLine to remove the auto-loaded PSReadLine module.
  • Run Import-Module PSReadLine (use PSReadLine with capital L).
  • Then run Update-Help -Module PSReadLine -Force"

- unfortunately I still have error:

 

PS C:\WINDOWS\system32> Remove-Module PSReadLine
PS C:\WINDOWS\system32> Import-Module PSReadLine
PS C:\WINDOWS\system32> Update-Help -Module PSReadLine -Force
Update-Help : Failed to update Help for the module(s) 'PSReadLine' with UI culture(s) {en-US} : Unable to connect to He
lp content. The server on which Help content is stored might not be available. Verify that the server is available, or
wait until the server is back online, and then try the command again.

    + CategoryInfo          : InvalidOperation: (:) [Update-Help], Exception

PS C:\WINDOWS\system32>

 

Please kindly help to sort it out.

I am in company network behind Firewalls and Proxy.

 

Should we open some specific connection, for example, this?

51.104.176.40:443 SYN_SENT

 

 

I am on Windows 11 _x64_Ent

 

Thanks!

The IP Address is from Microsoft, and if you see SYN_SENT then you already know that it can't be reached because of your firewall. But you are able to install it, so you do have access to psgallery.com?

      Could you try Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Confirm:$false -Force:$true ?

        Your command worked fine, there was no error.

        Then I found such a cool https://stackoverflow.com/questions/43323123/warning-unable-to-find-module-repositories, where it was explain, how to work around, when you a behind a proxy server:

         

        You would indeed need to run:

        notepad $profile

         

        and copy paste this bit changing my proxy details:

        [system.net.webrequest]::defaultwebproxy = new-object system.net.webproxy('http://webproxy.yourCompany.com:PORT')
[system.net.webrequest]::defaultwebproxy.credentials =  System.Net.CredentialCache]::DefaultNetworkCredentials
[system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true

         

        After that I run

         

        PS C:\WINDOWS\system32> Get-PSRepository

         

        and got positive results:

        Later was able to run

        PS C:\WINDOWS\system32> update-help

        it updated many components, but not all.

         

        Still unable to update this part:
