Knowing how to script Windows feature management is valuable for IT support, system administration, and automation roles.

1

List Installed Windows Features

Write a PowerShell command to get all Windows features and store them in a variable called features.

PowerShell

# Your code here

Need a hint?

Use the Get-WindowsFeature cmdlet to list all features.

2

Set Feature to Manage

Create a variable called featureName and set it to the string 'Telnet-Client' to specify the feature you want to manage.

PowerShell

$features = Get-WindowsFeature
# Your code here

Need a hint?

Assign the feature name as a string to the variable featureName.

3

Install or Remove the Feature

Write an if statement that checks if the feature named featureName is installed by looking in $features. If it is installed, remove it using Remove-WindowsFeature. If it is not installed, install it using Install-WindowsFeature.

PowerShell

$features = Get-WindowsFeature
$featureName = 'Telnet-Client'
# Your code here

Need a hint?

Use Where-Object to find the feature by name and check its Installed property.

4

Display Updated Feature Status

Run Get-WindowsFeature again for the feature named featureName and print its name and installation status using Write-Output.

PowerShell

$features = Get-WindowsFeature
$featureName = 'Telnet-Client'
if ($features | Where-Object { $_.Name -eq $featureName -and $_.Installed }) {
    Remove-WindowsFeature -Name $featureName
} else {
    Install-WindowsFeature -Name $featureName
}
# Your code here

Need a hint?

Use Get-WindowsFeature -Name $featureName and Write-Output to show the feature status.
