Why is Xampp not running in my Windows 7?
There is any one of a number of reasons why this may happen, but the more common reasons are simple, Windows 7 automatically starts IIS as a service. As a consequence, there is a conflict between the Xampp installed Apache and IIS, so Windows 7 assigns preference to IIS and will not see Apache. You can stop IIS before Windows 7 starts it up in the configuration files. An alternative is to reset the port that IIS listens to to something other than Port 80 in the IIS ini file. The other reasons the Windows 7 refuses to allow Xampp to run are often based around permissions.
