How to Fix wdf01000.sys Errors

Fortunately, wdf01000.sys is such a common piece of software that preventing, or fixing, the error is consistent across versions of Windows.

  1. Use System Restore. Restore your computer to a previous System Restore point and reinstall any new software or drivers you may have added. By restoring the computer to an earlier time, you might strip away the update or code that's causing the error.

  2. Disconnect all devices and reboot your computer. Reconnect each device until the error recurs, then update that device's drivers. This helps you isolate the driver that is causing the error. While it might take a little extra time to check each component, it should take you right to the source of the problem.

  3. Scan for malware and perform any repair actions required. Malware can cause all manner of errors and issues with a computer. A regular, deep malware scan could also prevent or stop many problems.

  4. Use Device Manager to check for corrupted or outdated drivers. These will be highlighted with a yellow exclamation point. A corrupted or outdated driver will cause this kind of issue and updating the driver should stop the error and any problems associated with it.

  5. Use the Windows System File Checker (SFC) to repair corrupted files. Corrupt files are just as bad (or maybe worse) than outdated files. If you have corrupted files on your system, they can cause errors and problems with any other software also on the system.

  6. Run Check Disk to scan for damaged files. Damaged files are similar to corrupt files, except that with a damaged file there is something missing, usually. In many cases, checking your system with Check Disk will help isolate and repair these issues.

  7. Re-register wdf01000.sys using the System Registry.

    Always locate your reinstallation files and backup your system before you begin making changes to the registry. The registry is a complicated part of the Windows Operating System, and making changes to the wrong thing can create bigger issues.

  8. Re-install Windows and restore your files from backups. When all else fails, the nuclear option will often stop the problem from happening again. Just be aware that re-installing Windows will mean everything on the computer is erased, so be sure you have a current backup of all your files and applications before you begin.
