How can i solve the error when running xampp saying that the port/s are in use by another program?

Question

I have xampp v 3.2.1 and i'm getting this error in red:

You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Problem detected! Port 21 in use by "C:\WINDOWS\system32\svchost.exe -k ftpsvc"! FileZilla WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure FileZilla and the Control Panel to listen on a different port

Answer 1

Disable the FTP Server that is already running (most likely running via Windows Add/Remove Programs -> Windows Features). Otherwise, you will need to change the port in the FileZilla settings located at %APPDATA%/FileZilla
