Solução
Step 2
Für Windows ME und XP Benutzer: Stellen Sie vor einer Suche sicher, dass die Systemwiederherstellung deaktiviert ist, damit der gesamte Computer durchsucht werden kann.
Step 3
<p> Beachten Sie, dass nicht alle Dateien, Ordner, Registrierungsschlüssel und Einträge auf Ihrem Computer installiert sind, während diese Malware / Spyware / Grayware ausgeführt wird. Dies kann auf eine unvollständige Installation oder andere Betriebssystembedingungen zurückzuführen sein. Fahren Sie mit dem nächsten Schritt fort. </ p><p> Beachten Sie, dass nicht alle Dateien, Ordner, Registrierungsschlüssel und Einträge auf Ihrem Computer installiert sind, während diese Malware / Spyware / Grayware ausgeführt wird. Dies kann auf eine unvollständige Installation oder andere Betriebssystembedingungen zurückzuführen sein. Fahren Sie mit dem nächsten Schritt fort. </ p>
Step 4
Diesen Registrierungswert löschen
Wichtig: Eine nicht ordnungsgemäße Bearbeitung der Windows Registrierung kann zu einer dauerhaften Fehlfunktion des Systems führen. Führen Sie diesen Schritt nur durch, wenn Sie mit der Vorgehensweise vertraut sind oder wenn Sie Ihren Systemadministrator um Unterstützung bitten können. Lesen Sie ansonsten zuerst diesen Microsoft Artikel, bevor Sie die Registrierung Ihres Computers ändern.
