"Die Software hat kein sichtbares Fenster." das stimmt nicht. PRTG kann als NT-Dienst und als Windows GUI Programm verwendet werden. PRTG enthält einen eigenen Webserver und verwendet SNMP und PING zur Netzwerküberwachung. Außerdem kann es NETFLOW Daten entgegennehmen und verarbeiten. PRTG manipuliert keine anderen Programme.

Best practices for resolving PRTG Traffic Grapher issues

A clean and tidy computer is the key requirement for avoiding problems with PRTG Traffic Grapher. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
