Resource do not work on Windows 10

[FrelVick]

Due to this function Assert-HasPrereqsForBitlocker the resource doesn't start on the Windows 10. If you perform all the steps manually it works perfectly.

Since Get-WindowsFeature doesn't exists on client OS the function throw

'Required Bitlocker features need to be installed before xBitlocker can be used'

which is not true for Pro, Enterprise, and Education editions of Windows 10.

if( ((Get-CimInstance -ClassName Win32_OperatingSystem).ProductType -eq 1) -and (get-command enable-bitlocker -ErrorAction SilentlyContinue)) then {It is a workstation with BitLocker available, don't throw}

Little check like that one could help you to avoid false negative assert.

Looks like a bug to me. Thanks for the report!

Can someone add the missing if statement and updated code as from FrelVick proposed.

`
function Assert-HasPrereqsForBitlocker
{
[CmdletBinding()]
param()

    $hasAllPreReqs = $true

    # 1 - Client   
    # 2 - Domaincontroller   
    # 3 - Server
    $osProductType = (Get-CimInstance -ClassName Win32_OperatingSystem).ProductType
    if ($osProductType -eq 1)
    {
        if (!(get-command enable-bitlocker -ErrorAction SilentlyContinue))
        {
            $hasAllPreReqs = $false
        }
    }
    else
    {
        $blFeature = Get-WindowsFeature BitLocker
        $blAdminToolsFeature = Get-WindowsFeature RSAT-Feature-Tools-BitLocker
        $blAdminToolsRemoteFeature = Get-WindowsFeature RSAT-Feature-Tools-BitLocker-RemoteAdminTool

        if ($blFeature.InstallState -ne 'Installed')
        {
            $hasAllPreReqs = $false

            Write-Error 'The Bitlocker feature needs to be installed before the xBitlocker module can be used'
        }

        if ($blAdminToolsFeature.InstallState -ne 'Installed')
