I installed XAMPP (1.8, windows 7), deactivated the User Account Control as promtped and tried again, was getting error

Error: Apache shutdown unexpectedly.
12:35:35 [Apache] This may be due to a blocked port, missing dependencies,
12:35:35 [Apache] improper privileges, a crash, or a shutdown by another method.
12:35:35 [Apache] Check the "/xampp/apache/logs/error.log" file
12:35:35 [Apache] and the Windows Event Viewer for more clues

NETSTAT



and their is not "/xampp/apache/logs/error.log" file because apache does not start yet

thank you for help

Ummm, yes its not working because 'system' is using port 80 (that would mean, almost certainly, that the httpd.sys driver is at work)

- most likely - you have either

IIS running (whether or not you are aware of it)
or
A Web management interface for a MS server software running - a likely candidate MSSQL Server

Windows Task Manager > Performance > Resource Monitor > Listening Ports will tell you what is on Port 80

Both use the httpd.sys streamer (which is a core driver) - so 'system' is reported as the executable/service that is running.

Google 'httpd.sys'

Port 80 in use by "system" for this problem disable the service

Open "SERVICES.MSC"
Stop "Web Deployment Agent Service"

Now you start Apache Service
