Powershell: How do I install the Nuget provider for PowerShell on a unconnected machine so I can install a nuget package from the PS command line?

Although I've tried all the previous answers, only the following one worked out:

1 - Open Powershell (as Admin)

2 - Run:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

3 - Run:

Install-PackageProvider -Name NuGet

I accepted trebleCode's answer, but I wanted to provide a bit more detail regarding the steps I took to install the nupkg of interest pswindowsupdate.2.0.0.4.nupkg on my unconnected Win 7 machine by way of following trebleCode's answer.

First: after digging around a bit, I think I found the MS docs that trebleCode refers to:

Bootstrap the NuGet provider and NuGet.exe

Install-PackageProvider

To continue, as trebleCode stated, I did the following

Install NuGet provider on my connected machine

On a connected machine (Win 10 machine), from the PS command line, I ran Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.208 -Force. The Nuget software was obtained from the 'Net and installed on my local connected machine.

After the install I found the NuGet provider software at C:\Program Files\PackageManagement\ProviderAssemblies (Note: the folder name \ProviderAssemblies as opposed to \ReferenceAssemblies was the one minor difference relative to trebleCode's answer.

The provider software is in a folder structure like this:

C:\Program Files\PackageManagement\ProviderAssemblies
   \NuGet
      \2.8.5.208
         \Microsoft.PackageManagement.NuGetProvider.dll
     

Install NuGet provider on my unconnected machine

I copied the \NuGet folder (and all its children) from the connected machine onto a thumb drive and copied it to C:\Program Files\PackageManagement\ProviderAssemblies on my unconnected (Win 7) machine

I started PS (v5) on my unconnected (Win 7) machine and ran Import-PackageProvider -Name NuGet -RequiredVersion 2.8.5.208 to import the provider to the current PowerShell session.

I ran Get-PackageProvider -ListAvailable and saw this (NuGet appears where it was not present before):

Create local repository on my unconnected machine

On unconnected (Win 7) machine, I created a folder to serve as my PS repository (say, c:\users\foo\Documents\PSRepository)

I registered the repo: Register-PSRepository -Name fooPsRepository -SourceLocation c:\users\foo\Documents\PSRepository -InstallationPolicy Trusted

Install the NuGet package

I obtained and copied the nupkg pswindowsupdate.2.0.0.4.nupkg to c:\users\foo\Documents\PSRepository on my unconnected Win7 machine

I learned the name of the module by executing Find-Module -Repository fooPsRepository

I installed the module by executing Install-Module -Name pswindowsupdate

I verified the module installed by executing Get-Command –module PSWindowsUpdate
