I couldn't find the Native Utilities either. However I think I found a workaround. I was trying to setup on Windows Server 2003, so these instructions are for that platform. I bet you could do just about the same thing on other versions of Windows though.
1. Download the Windows Server 2003 Resource Kit Tools from here.
2. After installing, create a new Windows Service named <NameOfService> (I chose to name it JBoss on my system) by running this command in the command line:
"<PathToResourceKitTools>\instsrv.exe" <NameOfService> "<PathToResourceKitTools>\srvany.exe"
NOTE: on my machine <PathToResourceKitTools> was "C:\Program Files (x86)\Windows Resource Kits\Tools\"
3. Now open Registry Editor by running "regedt32.exe" or "regedit"
4. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<NameOfService>
NOTE: on my machine this was HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\JBoss
5. From the Edit menu add a new Key named "Parameters"
6. Select the Parameters key and from the Edit menu add a String Value named "Application"
7. Double click on the Application value and in the "Value data" box enter: <PathToJBossFolder>\bin\standalone.bat
NOTE: the <PathToJBossFolder> will be wherever you placed the JBoss EAP 6.x folder you extracted from the zip archive
8. Close the Registry Editor and open "services.msc"
9. You will see <NameOfService> as a service in the list - double click it
10. Select "Startup type" of Automatic, and then click the "Start" button
I think that this will do what you want.
