First, see if it will run correctly
Use the Control Panel and click the start buttons for Apache and MySQL (and filezilla if you need it) and see if they will start.
Your firewall may also prompt you to allow the applications to run, OK that choice.
If you get the Green "Running" on both, see if you can open the XAMPP Welcome page (http://localhost
If that works and you can run some of the samples, stop Apache, MySQL etc in the Control Panel.
Now click on th Service button for each in turn, it will ask you if you want to make them into services. Yes/OK for that -
reboot and see if they start correctly. Note you do not have to make them services, that is strictly to automatically start them when you reboot. You can start them manually with the Control Panel or use its 'Config' to auto-start Apache/MySQL etc, when the Control Panel starts.
