Thanks everyone for trying to help me.

I fixed that issue with IIS.
First, I uninstalled IIS as a component, and then reinstalled it again.
While I rebooted the system it starded fixing bad files and references, and I assume the system was corrupted. But anyway, now I know how to fix it.
If anyone have similar issues, I will give my advice.

Have a great day,
Peter
