Dear members,
I have just installed xampp and while starting the server I received the following;

10:02:29 AM [main] most application stuff but whenever you do something with services
10:02:29 AM [main] there will be a security dialogue or things will break! So think
10:02:29 AM [main] about running this application with administrator rights!
