# Get PowerShell 5.1 up to date

Always have your PowerShell 5.1 up to date with the latest NuGet, PackageManagement, and PowerShellGet modules and providers.

# Admin, admin, admin

Be sure to always run commands in an elevated PowerShell session. Use the below command to check if your current session is running as an administrator:

([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

# Set Execution Policy

Use the below command to set the execution policy to RemoteSigned if it is not already set. Bypass will work too if you are feeling risky.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force

# Install NuGet

Use the below command to install the NuGet provider if it is not already installed.

if ($(Get-PackageProvider).Name -notcontains "NuGet") {
    Install-PackageProvider -Name NuGet -Force
}

# Install PackageManagement

Use the below command to install the PackageManagement module if it is not already installed.

$InstalledModule = Get-Module -Name PackageManagement -ListAvailable | Where-Object { $_.Version -ge '1.4.8.1' }
if (-not ($InstalledModule)) {
    Install-Module -Name PackageManagement -Force -Scope AllUsers -AllowClobber -SkipPublisherCheck
}

# Install PowerShellGet

Use the below command to install the PowerShellGet module if it is not already installed.

$InstalledModule = Get-Module -Name PowerShellGet -ListAvailable | Where-Object { $_.Version -ge '2.2.5'}
if (-not ($InstalledModule)) {
    Install-Module -Name PowerShellGet -Force -Scope AllUsers -AllowClobber -SkipPublisherCheck
}

# Close PowerShell

Close the PowerShell window and open a new one to ensure the changes take effect when running subsequent commands.
