Quick overview:
When it comes to security, the developers have worked hard under the hood and given Windows 8 new functions - which significantly enhance the OS compared to its predecessor. Windows Tweaks presents the security features. Let's start with the file version history, i.e. Microsoft's "Time Machine". This brings deleted files back to life and restores previous versions.
Version history for deleted files and old versions
Apple users have the Time Machine, Windows 8 users the File Version History. This data recovery function automatically backs up files and intermediate versions to external data carriers such as USB sticks or network hard disks. Once activated, Windows 8 backs up edited files once an hour, although other intervals can also be selected. Recovery in an emergency is done with just a few clicks.
With the file version history, you can...
- ...recover deleted files: Accidentally "deleted" a file irrevocably? With the version history, you can restore an earlier version of the folder in which the file was saved with just a few clicks.
- ...restore previous versions: Accidentally saved a file even though the previous version was better? No problem, you can undo bad changes with just a few clicks. Old versions can be easily restored.
How to set up the file version history
1. Damit der Dateiversionsverlauf arbeitet, braucht Windows eine zweite Festplatte. Dabei kann sich es sich um USB-Laufwerke oder Netzwerkfestplatten handeln. Tippen Sie auf die „Windows“-Taste, um zum neuen Startbildschirm zu gelangen. Tippen Sie dann „Dateiversionsverlauf“ ein, wodurch die Suchfunktion loslegt. Es folgen Klicks auf „Einstellungen“ und dann auf „Dateiversionsverlauf“.

2. Wählen Sie nun „Laufwerk auswählen“ und entscheiden sich für das Sicherungslaufwerk zum Speichern der Dateien. Klicken Sie auf „OK“. Zurück im Dateiversionsverlaufs-Fenster klicken Sie dann noch auf „Einschalten“. Es erscheint die Meldung „Dateiversionsverlauf ist eingeschaltet“. Ab sofort speichert Windows 8 nun alle Dateien und Ordner in Ihren Bibliotheken, im SkyDrive Ordner und auf der Arbeitsoberfläche, sowie die Lesezeichen des Internet Explorers.
