Do you mean that as well as Apache 2.2 you have also installed XAMPP?

Right click on xampp-portcheck.exe (in the xampp installation folder if you have got that far) and select to run as an administrator - but may not tell you what you want to know in Vista or you can use netstat or tcpview - your Windows Help could be useful to learn how to use the last 2 or try:
Start -> Run -> type cmd
Next type netstat -anop TCP
Check the PID number with the Task Manager>Processes tab.
Culprits may be Skype - change the port configuration in Skype and or IIS - see above how to disable it.
