I am using XAMPPS to host PHP files from my machine. I have recently installed XAMPPs but I am unable to start Apache service as port 80 is in use by PID 4 - NT Kernel & System.

I know by using a different port (such as port 8080 etc change in httpd.conf) will get to a workaround for this issue. However I need port 80 to be released by PID 4 process and allocated to Apache service. I have done that in the past but have forgotten the resolution steps over the time. Please help me fix it
