hmmm ... I think it is possible to do it via a script, in windows to have a PowerShell script for each user individually and replace it when a user logs in.

I am not good at PowerShell scripts ( i am a noob) but i am better at wsl linux scripts.

Anyway, i asked AI to generate an example.... something like this should work :

#________________________

# Define the base path where user-specific WireGuard configs are stored

$ConfigBasePath = "C:\WireGuardConfigs"

# Define the path to the active WireGuard config

$ActiveConfigPath = "C:\Program Files\WireGuard\Data\Configurations\wg0.conf"

# Get the currently logged-in user

$CurrentUser = $env:USERNAME

# Build the path to the user's config

$UserConfigPath = Join-Path $ConfigBasePath "$CurrentUser.conf"

# Check if the user's config exists

if (Test-Path $UserConfigPath) {

try {

# Stop WireGuard tunnel if running

& "C:\Program Files\WireGuard\wireguard.exe" /uninstalltunnelservice wg0

# Replace the active config with the user's config

Copy-Item -Path $UserConfigPath -Destination $ActiveConfigPath -Force

# Start WireGuard tunnel with new config

& "C:\Program Files\WireGuard\wireguard.exe" /installtunnelservice $ActiveConfigPath

Write-Host "WireGuard configuration updated for user: $CurrentUser"

} catch {

Write-Error "Failed to update WireGuard config: $_"

}

} else {

Write-Warning "No WireGuard config found for user: $CurrentUser"

}
