Hello,

Do you need to recover WiFi connection passwords for your Windows computer?

A bit of PowerShell code can meet your need.

# To be executed in administrator to be sure to have access to the key
# In user mode some keys are not displayed
$WlanProfiles = netsh wlan show profiles |
Select-String "Profile " | ForEach-Object { ($_.Line -split ': ',2)[-1]}
Foreach ($WlanProfile in $WlanProfiles) {
    $KeyProfile = netsh wlan show profile name=$WlanProfile key=clear | Select-String 'Contents of' $KeyProfile = netsh wlan show profile name=$WlanProfile key=clear | Select-String 'Key Content'
    $Password = if ( $null -ne $KeyProfile ) { $KeyProfile.ToString().Split(': ')[-1] }
    [PSCustomObject]@{
        Profile = $WlanProfile
        Password = $Password
    }
}

# Installing a Powershell module to manage WiFi profiles
Install-Module wifiprofilemanagement

# Display profiles and their passwords
# Run as administrator to ensure you have access to the key
Foreach ($WlanProfile in (Get-WiFiProfile)) {
    Get-WiFiProfile -ProfileName $WlanProfile.ProfileName -ClearKey |
        Select-Object ProfileName,Password
}
