After the automatic migration from Windows 7 to Windows 10 I got the Apache start problem according to the XAMPP Control Panel:
16:25:28 [main] Initializing Control Panel
16:25:28 [main] Windows Version: Windows 8 64-bit
16:25:28 [main] XAMPP Version: 5.6.8
16:25:28 [main] Control Panel Version: 3.2.1 [ Compiled: May 7th 2013 ]
16:25:28 [main] You are not running with administrator rights! This will work for
16:25:28 [main] most application stuff but whenever you do something with services
16:25:28 [main] there will be a security dialogue or things will break! So think
16:25:28 [main] about running this application with administrator rights!
16:25:28 [main] XAMPP Installation Directory: "c:\xampp\"
16:25:28 [main] Checking for prerequisites
16:25:31 [main] All prerequisites found
16:25:31 [main] Initializing Modules
16:25:31 [Apache] Problem detected!
16:25:31 [Apache] Port 80 in use by "Unable to open process" with PID 4!
16:25:31 [Apache] Apache WILL NOT start without the configured ports free!
16:25:31 [Apache] You need to uninstall/disable/reconfigure the blocking application
16:25:31 [Apache] or reconfigure Apache and the Control Panel to listen on a different port
16:25:31 [main] The FileZilla module is disabled
16:25:31 [main] The Mercury module is disabled
16:25:31 [main] The Tomcat module is disabled
16:25:31 [main] Starting Check-Timer

That problem does however NOT occur at my other pc which has been migrated from Windows 8 (eight) to Windows 10!
What should I to do in order to fix the above mentioned problem at my pc which has been migrated from Windows 7 (seven) to Windows 10!
