Quick overview:

Sie erhalten beim Windows-Systemstart oder während der Arbeit kuriose Meldungen über defekte, "illegale" oder fehlende Systemdateien? Der "Windows File Checker" kann weiterhelfen! [Sandro Villinger]

Er prüft die wichtigsten Systemdateien und ist in der Lage, diese durch (separat gesicherte) Dateien zu ersetzen und somit das System in einen funktionsfähigen Zustand zu versetzen.

1. Klicken Sie zum Check auf "Start/Alle Programme/Zubehör" und mit der rechten Maustaste auf "Eingabeaufforderung". Wählen Sie hier "Als Administrator ausführen". Bei XP genügt es, wenn Sie einfach mit der linken Maustaste auf "Eingabeaufforderung" klicken.

2. Geben Sie "sfc /scannow" ein. Nach circa 3-5 Minuten ist die Überprüfung abgeschlossen und defekte Systemdateien sind repariert.

Viele Probleme mit Windows können auf diese Weise sicher gelöst werden.

Founded Windows Tweaks as a teenager in the 90s. His helpful PC tricks made it Germany's most visited Windows site (at the time Sandro looked like this). He then went on to write elsewhere, for example for PC-Praxis, Computer Bild and PCWorld in the USA. Microsoft also poached him from us. Now Sandro is back, finally sharing his tweaks here again. For a stress-free digital everyday life. You can reach Sandro via e-mail.

  1. The reason for this: Utilman.exe is, as far as I know, a file that hackers have used in the past to gain control of the PC. With an update and XP SP3, this file was deleted and is therefore no longer available! So it is actually quite good that it could not be restored.

  2. Hello,

    I am experiencing the following problems when trying to repair the system using a CD. After entering computer repair options, it does not continue.
    Error message: Path not found!
    Also: Windows\systemm32\cmd.exe could not be found.
    Do you know a remedy? Thanks and regards Bodo [difev@web.de]
