Die datei fiel mir auf durch einen extrem hohen Leistungsverbrauch.Sie öffnet sich (im Task Manager sichtbar) beim Einschalten nur wenn Internet Anschluss vorhanden, sodass ich annehme, sie wird vom Internet eingespielt. Sie lässt sich im task manager löschen, muss aber 3mal gelöscht werden. -- Wozu benutzt Windows denn diese Datei ? MIt dem Windows Suchprogramm ist sie nicht auffindbar.

Bei aktivem Progr. belegt es 50% Speicher. Schaltet man es aus über den Taskmanger ist der Speicher wieder 100%. Der Rechner verliert an Rechengeschwindigkeit und das extrem. Desweiteren sendet das Programm stetig keine Datenmengen. Es kann sich nur um Datenspionage handeln.

Best practices for resolving WPFFontCache_v0400 issues

A clean and tidy computer is the key requirement for avoiding problems with WPFFontCache_v0400. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
