Updating PowerShellGet for Windows PowerShell 5.1
PowerShellGet requires .NET Framework 4.5 or above. For more information, see Install the .NET Framework for developers.
To access the PowerShell Gallery, you must use Transport Layer Security (TLS) 1.2 or higher. By default, PowerShell is not configured to use TLS 1.2. Use the following command to enable TLS 1.2 in your PowerShell session.
[Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12
We also recommend adding this line of code to your PowerShell profile script. For more information about profiles, see about_Profiles.

If you have not configured TLS 1.2, any attempts to install the NuGet provider and other packages will fail.
After installing PowerShellGet
After you have installed the new version of PowerShellGet, you should open a new PowerShell session. PowerShell automatically loads the newest version of the module when you use a PowerShellGet cmdlet.
We also recommend that you register the PowerShell Gallery as a trusted repository. Use the following command:
Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
