[xampp] Localhost : 404 not found

Type in "netstat -ano" into your command line. I saw that it was showing something for Local Address port 0.0.0.0:80.

My issue was because I had SQL Server Reporting Services on Port 80. So I followed these instructions and changed the port # from 80 to 81:

Here is a picture of my command line after I changed the port number for SQL Server Reporting Services:
