Xammp was hacked?

My website was running good on local machine for almost 3 months, but than out of nowhere i couldn't access my website through domain.What got my attention is,that i couldn't access anything i had in xampp htdocs directory,even when i used http://local/...... it just shows
this error :

When i have checked my xampp apache error logs,i found some suspicious error notices and i am 99% sure thats hack attempt logs,but i really have no clue what happened.

Website stopped running on October 20th and here are the logs with suspicious activites :

Any thoughts or similar experiences???

first screen is IIS 404 error and second its apache log, i don't get it.
Uninstall IIS and then reinstall/repair xampp.

As i said,website was running just fine for almost 3 months on xampp and i havn't applied any changes in my operation system or any kind of upates or any edit and customizations elsewhere and my site just stopped working for no reason.Moments before that,site was barely loading itself and than it loaded randomly like 1 out of 20 times.From next day,i can't access anything anymore that is in my xampp htdocs,even though files are there!!Also when i go to my domain,i get IIS7 Welcome screen and than i end up at their official site instead of my website.

If you use windows server system then go to Start->Administrative Tools->Server Manager and disable/uninstall IIS role, restart the server and try to run xampp.

This fixed my problem,but i still wonder what and why it happened in the first place?Probably Win7 bug.
