I have installed a few previous versions of Xampp on my computer, in order to upgrade an old joomla site that had compatibility issues with PHP 7.3, so I needed a Xampp installation with PHP 5.4(if I remember correctly).
Thus I installed a version, upgraded the joomla installation as far as i could, did a backup of the site, uninstalled Xampp, installed a newer version, repeat... until the website was compatible with PHP 7.3.
Each time I installed Xampp, I had to use a different port than the previous version I had installed, because the port was being block by System (PID 4).
I uninstalled each previous version through control panel(i know the recommended way is with the uninstaller, but I just saw that just today, I thought Control Panel would do the trick), before installing a newer version.
How do I get those ports open, to be reused? I do not have IIS, and no other program that could block those ports. Currently ports 80, 8080, 8082, 8083 cannot be used with Xampp.
I know I can just edit the config file and use a different port, but is there any way to release those ports? I've tried "CurrPorts", "TCPView" etc. to close the connections to no avail.
Any ideas?
