AFC klingt sich als Laufwerktreiber bei CD und DVD Laufwerken ein. Wenn er gelöscht wird, dann hat man keine Zugriff mehr zum DVD/CD - LW. Wenn man ihn löscht, dann sollte man sich den Gerätemanager ansehen, das/die Laufwerk/e löschen. In der Registry müssen alle Einträge entfernt werden in denen AFC.SYS erscheint. Danach im Windows/System32/driver32 den Treiber für alle Fälle Speichern. Im Windowsverzeichnis nach weiteren Einträgen suchen (z.B. ntbtlog.txt) und ausscheiden und woanders speichern. Danach über Systemsteuerung/Hardware neu installieren. Das trifft übrigens auch für PFC.SYS zu.
Verhinderte, dass DVD-RAM Treiber funktioniert. AFC aus Lowerfilters in der Registry entfernt

Best practices for resolving Afc issues

A clean and tidy computer is the key requirement for avoiding problems with Afc. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
