apache not starting

I don't think that stopping IIS is enough.  I think that it still owns port 80 as long as it is installed.  It also doesn't do any good to change the IP address IIS uses, it still hogs port 80.

To change Apache to Listen 8080, you may have to restart the machine, not just the web server.

Your graphic shows that a process with the PID of 4 still has hold of port 80. Have a look at the task manager (or run tasklist from command prompt) and it'll show you which application is running with a PID of 4. May help you track things down

DaveBaldwin: I tried restarting the computer but no use

seth2740: PID 4 is system ( If I change the value to 4 and reboot My .net related program will continue? I mean its safe , please confirm)

yes...it's probably coming from windows remote management service or something related to that
i have the same service on my system and is disabled

Yes seth2740,  port issue resolved.

It still says now:
07:07:32  [Apache]       Apache Service detected with wrong path
07:07:32  [Apache]       Change XAMPP Apache and Control Panel settings or
07:07:32  [Apache]       Uninstall/disable the other service manually first
07:07:32  [Apache]       Found Path: "Z:\xampp\apache\bin\httpd.exe" -k runservice
07:07:32  [Apache]       Expected Path: "c:\xampp\apache\bin\httpd.exe" -k runservice
 
reason being Once(some previous time say one month back) I installed xampp in Z directory but to remove the error in the current comment ,I deleted the xampp folder in Z drive I am not sure How its still looking for that path? (and yesterday I again installed the xampp in c drive)
