XAMPP 1.7.7 - Apache won't start (ports already changed)

Question

I installed XAMPP 1.7.7 for testing on the old php version. Current XAMPP is running fine. I changed the ports in httpd.conf from 80 to 8081, and in httpd-ssl.conf from 443 to 4434.

Still, when trying to start apache, I get the error

"error: apache was stopped unexpected. This might be caused by a blocked port, missing dependencies,..."

I also changed these ports again (they were not used in both cases).

I run XAMPP as an administrator and I disabled my firewall without any results... What are other possible options? (Error-)Logs are empty.

maybe the following information might help: I am using windows 10, xampp 1.7.7 portable, and although I changed the ports, when I run XAMPP, it tells me the following:

Problem detected!
Port 80 in use by "Unable to open process" (PID 4)!
Apache will NOT start without the configured ports free!

Try to do this:

Run -> CMD, type services.msc and stop the program: Web Deployment Agent Service

Afterwards try restarting XAMPP and say if it works or not!
