How do I get PowerShell 4 cmdlets such as Test-NetConnection to work on Windows 7?

Question

The situation. On a Windows 7 SP1 machine, I have updated with Windows6.1-KB2819745-x64-MultiPkg.msu. Furthermore, in PowerShell $PSVersionTable now reports ‘PSVersion 4.0’.

Answer 1

At least Test-NetConnection can be ported back to Windows 7. Just copy folders NetTCPIP, DnsClient, and NetSecurity from the supported Windows machine with the same PowerShell version (Windows 8.1, Windows 10, etc). Folder - C:\Windows\System32\WindowsPowerShell\v1.0\Modules. Then Import-Module -Name C:\Windows\System32\WindowsPowerShell\v1.0\Modules\NetTCPIP -Verbose

Alternatively, you can import a module from a remote machine (say win2012):

$rsession = New-PSSession -ComputerName win2012
Import-Module NetTCPIP -PSSession $rsession

I have had the same problem on my Windows 7 x64 and both solutions worked for me as of PowerShell 5.1.
