Install PowerShell 5.0, Nuget and download cmdlets behind proxy

I had to prepare corporate Windows 7 PC behind proxy to be able to work with the SharePointPnPPowerShellOnline cmdlets. Here are the steps that I performed to get there. Windows administrator account will be needed.

Install Windows Management Framework 5.0 (WMF)

Go to the Microsoft Download center, download Windows Management Framework 5.0
from this link and install it. The installation requires reboot of the PC.
After the reboot open the PowerShell command shell window as administrator and verify the version of the installed PowerShell.

The output should be similar to what I have below:
Major  Minor  Build  Revision
-----  -----  -----  --------
5      0      10586  117

Set up proxy credentials

What I did to make it work for me is executing those two commands.
$wc = New-Object System.Net.WebClient
$wc.Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
It is clear from my previous statement that I am not sure what this does. Of course as a hardcore true ninja developer I just used my most advanced skill, Copy-Paste indeed. Here is the link to the source. If you truly want to understand what it does, you can visit this link or this link.

Install the Nuget package provider

Check if nuget is available in the package providers by running the following command.
Get-PackageProvider -ListAvailable

Name                     Version          DynamicOptions
----                     -------          --------------
msi                      AdditionalArguments
PowerShellGet            PackageManagementProvider, Type, Scope, InstallUpdate, PackageManagementPr...
Programs                 IncludeWindowsInstaller, IncludeSystemComponent

If the above output is your case and nuget is not presented, you have to install it.
Install-PackageProvider -Name NuGet -MinimumVersion -Force

Here is my successful installation output:
Name                           Version          Source                         Summary
----                           -------          ------                         -------
nuget                 NuGet provider for the OneGet meta-pa...

Almost there, register the default repository for PowerShell modules

My attempt to install SharePointPnPPowerShellOnline failed again after the above steps so I had to also register default repository:
Register-PSRepository -Name "PSGallery" –SourceLocation "" -InstallationPolicy Trusted

Finally, install the SharePointPnPPowerShellOnline module

Install-Module SharePointPnPPowerShellOnline

Good to go! Have fun with the PnP-PowerShell cmdlets.

P.S. If you experience error 'UnauthorizedAccess,Microsoft.PowerShell.Commands.ImportModuleCommand' when running the SharePointPnPPowerShellOnline module then you may need to change the PowerShell execution policy.

Set-ExecutionPolicy RemoteSigned
