Unregistering the default repository–PS version dependent?

In this post – https://richardspowershellblog.wordpress.com/2016/09/17/powershell-repositories/ – I stated that you could unregister the default PowerShell repository. I also said that the statement in the documentation for Unregister-PSrepository that you couldn’t unregister PSGallery was incorrect.

A couple of readers have left comments stating that they tried it and got an error message stating that PSGallery can’t be unregistered.

I did my first test on Windows 10 latest preview build – build 14926

PS> $PSVersionTable

Name                           Value
—-                           —–
PSVersion                      5.1.14926.1000
PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
BuildVersion                   10.0.14926.1000
CLRVersion                     4.0.30319.42000
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

I’ve just test on Windows Server 2016 TP5

PS C:\Windows\system32> $PSVersionTable

Name                           Value
—-                           —–
PSVersion                      5.1.14300.1000
PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
CLRVersion                     4.0.30319.42000
BuildVersion                   10.0.14300.1000
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

The version of PowerShell 5.1 on Server 2016 TP5 doesn’t have the –Default parameter on Register-PSrepositiry but this works

Register-PSRepository -Name PSGallery -SourceLocation https://www.powershellgallery.com/api/v2/

It appears that the ability to unregister the default repository and then re-register it is an evolving feature in PowerShell 5.1

    Thanks Richard for the thorough detail on this behavior. I wonder what can be done for those of us that are stuck with 5.0.10586.117 for the foreseeable future? Do you think that default configuration is stored in a file or registry key somewhere that I could manually modify (yes, it is dirty, but what choice do I have?)

    Reblogged this on Code and commented:
    Thank to Richard for his deep research on this issue …

    I found a solution for those of us running 5.0.10586.117, see the solution here: https://markrobertjohnson.wordpress.com/2016/10/12/unregistering-the-default-repository-ps-version-dependent/

      Well, not really the solution to unregistering the default gallery (Still had issue with that, even modifying the XML config directly), but at least allows for modifying the default URLs…
