Method 1: Standard removal (try first)

function Remove-AllBluetoothDevices {
Write-Host “Removing all Bluetooth devices…” -ForegroundColor Yellow

# Get all Bluetooth devices
$btDevices = Get-PnpDevice | Where-Object { 
    $_.Class -eq "Bluetooth" -or 
    $_.FriendlyName -like "*Bluetooth*" -or
    $_.InstanceId -like "*BTHUSB*" -or
    $_.InstanceId -like "*BTHLE*"
}

foreach ($device in $btDevices) {
    try {
        Write-Host "Removing: $($device.FriendlyName)" -ForegroundColor Cyan
        $device | Disable-PnpDevice -Confirm:$false
        $device | Remove-PnpDevice -Confirm:$false
    }
    catch {
        Write-Warning "Failed to remove $($device.FriendlyName): $($_.Exception.Message)"
    }
}

}

Method 2: Registry nuclear option (use if Method 1 fails)

function Remove-BluetoothDevicesRegistry {
Write-Host “Nuclear option: Clearing Bluetooth registry…” -ForegroundColor Red

# Stop Bluetooth services first
$services = @("bthserv", "BthAvctpSvc", "BTHPORT")
foreach ($service in $services) {
    try {
        Stop-Service -Name $service -Force -ErrorAction SilentlyContinue
        Write-Host "Stopped service: $service" -ForegroundColor Green
    }
    catch {
        Write-Warning "Could not stop service: $service"
    }
}

# Clear paired devices from registry
$regPaths = @(
    "HKLM:\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Devices",
    "HKLM:\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys",
    "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Bluetooth\ExceptionDB"
)

foreach ($path in $regPaths) {
    if (Test-Path $path) {
        try {
            Remove-Item -Path $path -Recurse -Force
            Write-Host "Cleared registry path: $path" -ForegroundColor Green
        }
        catch {
            Write-Warning "Could not clear: $path"
        }
    }
}

# Restart services
foreach ($service in $services) {
    try {
        Start-Service -Name $service -ErrorAction SilentlyContinue
        Write-Host "Restarted service: $service" -ForegroundColor Green
    }
    catch {
        Write-Warning "Could not restart service: $service"
    }
}

}

Method 3: Device Manager approach (most thorough)

function Remove-BluetoothDevicesDevMgmt {
Write-Host “Using Device Manager approach…” -ForegroundColor Magenta

# Get all devices with Bluetooth-related hardware IDs
$allDevices = Get-CimInstance -ClassName Win32_PnPEntity | Where-Object {
    $_.DeviceID -like "*BTHUSB*" -or
    $_.DeviceID -like "*BTHLE*" -or  
    $_.DeviceID -like "*BTHENUM*" -or
    $_.Name -like "*Bluetooth*" -or
    $_.Description -like "*Bluetooth*"
}

foreach ($device in $allDevices) {
    try {
        Write-Host "Force removing: $($device.Name)" -ForegroundColor Yellow

        # Try to disable first
        $pnpDevice = Get-PnpDevice -InstanceId $device.DeviceID -ErrorAction SilentlyContinue
        if ($pnpDevice) {
            $pnpDevice | Disable-PnpDevice -Confirm:$false -ErrorAction SilentlyContinue
            Start-Sleep -Milliseconds 500
            $pnpDevice | Remove-PnpDevice -Confirm:$false -ErrorAction SilentlyContinue
        }

        # If that fails, try WMI removal
        $device.Delete()
        Write-Host "Successfully removed: $($device.Name)" -ForegroundColor Green

    }
    catch {
        Write-Warning "Failed to remove $($device.Name): $($_.Exception.Message)"
    }
}

}

Method 4: PowerShell + DevCon hybrid (if you have Windows SDK)

function Remove-BluetoothDevicesDevCon {
$devconPath = “${env:ProgramFiles(x86)}\Windows Kits\10\Tools\x64\devcon.exe”

if (Test-Path $devconPath) {
    Write-Host "Using DevCon for forced removal..." -ForegroundColor Blue

    # Remove all Bluetooth devices
    & $devconPath remove "*BTHUSB*"
    & $devconPath remove "*BTHLE*" 
    & $devconPath remove "*BTHENUM*"

    # Rescan hardware
    & $devconPath rescan
}
else {
    Write-Warning "DevCon not found. Install Windows SDK or use other methods."
}

}

Main execution function

function Force-RemoveAllBluetoothDevices {
param(
[switch]$Nuclear,
[switch]$DevMgmt,
[switch]$DevCon
)

Write-Host "=== Bluetooth Device Force Removal ===" -ForegroundColor White -BackgroundColor Blue

# Check if running as admin
if (-not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
    Write-Error "This script requires Administrator privileges. Run PowerShell as Administrator."
    return
}

if ($Nuclear) {
    Remove-BluetoothDevicesRegistry
}
elseif ($DevMgmt) {
    Remove-BluetoothDevicesDevMgmt
}
elseif ($DevCon) {
    Remove-BluetoothDevicesDevCon
}
else {
    # Standard approach
    Remove-AllBluetoothDevices
}

Write-Host "`nOperation complete. You may need to restart your computer." -ForegroundColor Green
Write-Host "To re-enable Bluetooth, go to Device Manager and scan for hardware changes." -ForegroundColor Cyan

}

Usage examples:

Force-RemoveAllBluetoothDevices # Standard removal

Force-RemoveAllBluetoothDevices -Nuclear # Registry clearing

Force-RemoveAllBluetoothDevices -DevMgmt # Device Manager approach

Force-RemoveAllBluetoothDevices -DevCon # DevCon approach (if available)
