Steps to reproduce

I noticed a discrepancy in the behavior of Install-Module vs Install-PSResource on Windows Server 2022 / Powershell 7.4. With Install-Module IISAdministration, IISAdministration is not installed as it detects it is already installed (Expected behavior). Whereas Install-PSResource does install the version from the Powershell Gallery.

Install-PSResource Steps

 Install-PSResource IISAdministration -Verbose
 Import-Module  IISAdministration -Verbose

Yields:

VERBOSE: All paths to search: 'C:\Users\azureuser\Documents\PowerShell\Scripts'
VERBOSE: Retrieving directories in the path 'C:\Users\azureuser\Documents\PowerShell\Modules'
VERBOSE: Retrieving directories in the path 'C:\Users\azureuser\Documents\PowerShell\Scripts'
VERBOSE: Attempting to search for packages in 'PSGallery'
VERBOSE: Checking if untrusted repository should be used

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its Trusted value by
running the Set-PSResourceRepository cmdlet. Are you sure you want to install the PSResource from 'PSGallery'?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "N"): y

Install-Module Steps

For reference here is the behavior with Install-Module

 Install-Module  IISAdministration -Verbose
 Import-Module  IISAdministration -PassThru | select Path

Yields:

PS C:\Users\azureuser> Install-Module IISAdministration -Verbose
VERBOSE: Using the provider 'PowerShellGet' for searching packages.
VERBOSE: The -Repository parameter was not specified.  PowerShellGet will use all of the registered repositories.
VERBOSE: Getting the provider object for the PackageManagement Provider 'NuGet'.
VERBOSE: The specified Location is 'https://www.powershellgallery.com/api/v2' and PackageManagementProvider is 'NuGet'.
VERBOSE: Searching repository 'https://www.powershellgallery.com/api/v2/FindPackagesById()?id='IISAdministration'' for ''.
VERBOSE: Total package yield:'1' for the specified package 'IISAdministration'.
VERBOSE: Performing the operation "Install-Module" on target "Version '1.1.0.0' of module 'IISAdministration'".

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its
InstallationPolicy value by running the Set-PSRepository cmdlet. Are you sure you want to install the modules from
'PSGallery'?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "N"): y
VERBOSE: The installation scope is specified to be 'CurrentUser'.
VERBOSE: The specified module will be installed in 'C:\Users\azureuser\Documents\PowerShell\Modules'.
VERBOSE: Version '1.1.0.0' of module 'IISAdministration' is already installed at 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\IISAdministration'.

PS C:\Users\azureuser> Import-Module IISAdministration -PassThru | select Path

Path
----
C:\Windows\system32\WindowsPowerShell\v1.0\Modules\IISAdministration\iisadministration.psm1

I think this is happening because PSResourceGet is not searching in C:\Windows\system32\WindowsPowerShell\v1.0\Modules.

Actually this also happens in Windows Powershell 5.1 as well:

PS C:\Users\azureuser> Install-PSResource IISAdministration -Verbose
VERBOSE: All paths to search: 'C:\Users\azureuser\Documents\WindowsPowerShell\Modules'
VERBOSE: All paths to search: 'C:\Users\azureuser\Documents\WindowsPowerShell\Scripts'
VERBOSE: Retrieving directories in the path 'C:\Users\azureuser\Documents\WindowsPowerShell\Modules'
VERBOSE: Retrieving directories in the path 'C:\Users\azureuser\Documents\WindowsPowerShell\Scripts'

In this particular instance this is problematic because the IISAdministration Nuget package has not been updated in years and it is packaged incorrectly / missing the WebAdministration.dll as described in this issue

I believe the Install-Module behavior is the correct one (especially since I didn't use AllowClobber)

Expected behavior

VERBOSE: Version '1.1.0.0' of module 'IISAdministration' is already installed at 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\IISAdministration'

Actual behavior

VERBOSE: Successfully installed package 'IISAdministration' to location 'C:\Users\azureuser\Documents\PowerShell\Modules'
