XAMPP apache server is not starting after Skype in

Question

I am getting following console logs:

1:14:33 PM  [apache]    Possible problem detected! 
1:14:33 PM  [apache]    Port 80 in use by "c:\program files (x86)\skype\phone\skype.exe"!
1:14:33 PM  [apache]    Possible problem detected! 
1:14:33 PM  [apache]    Port 443 in use by "c:\program files (x86)\skype\phone\skype.exe"!
1:14:33 PM  [main]  Starting Check-Timer
1:14:33 PM  [main]  Control Panel Ready
1:15:10 PM  [apache]    Starting apache app...
1:15:11 PM  [apache]    Status change detected: running
1:15:11 PM  [apache]    Status change detected: stopped

It says 'Status change detected: running' to 'stopped' right away. I have tried to:

• Turn Off Windows Firewall for internal networks
• Change Port 80 to 99 in httpd.conf file at two locations Listen:80 and ServerName localhost:80
• Change Port 443 to 445 in httpd.conf file at same two locations.
• Apache server is not installed as a Windows service on my machine.
• There is no error or access log generated for today's date.

Answer 1

got skype>>tools>>options>>advanced and remove the check on (use ports 80 & 443).
