Prior to updating to PowerShell version 5 make sure to be running the latest version of .NET Framework (.NET 4.6.1 as of this writing). See Checking .NET Versions.

Check Current Version of PowerShell
Run either $Host.Version or $PSVersionTable.PSVersion

Install latest version of .NET.

PowerShell 5 is part of Windows Management Framework (WMF) version 5 and can be downloaded from Microsoft (2008 R2 or 2012 R2). Select the correct download for your version of Windows Server and run the installer. After completion verify the version.

Start by downloading .NET 4.6.1 from Microsoft. Launch the installer – I typically do this by running the command

c:tempNDP461-KB3102436-x86-x64-AllOS-ENU.exe

from an elevated PowerShell. Accept the licensing agreement and wait….

Check Version(s) of .NET Installed
From an elevated PowerShell run the following set of commands:

Get-ChildItem 'HKLM:SOFTWAREMicrosoftNET Framework SetupNDP' -recurse |

Get-ItemProperty -name Version,Release -EA 0 |

Where { $_.PSChildName -match '^(?!S)p{L}'} |

Select PSChildName, Version, Release, @{

  name="Product"

  expression={

      switch($_.Release) {

        378389 { [Version]"4.5" }

        378675 { [Version]"4.5.1" }

        378758 { [Version]"4.5.1" }

        379893 { [Version]"4.5.2" }

        393295 { [Version]"4.6" }

        393297 { [Version]"4.6" }

        394254 { [Version]"4.6.1" }

        394271 { [Version]"4.6.1" }

      }

    }

}
