Fix Error 3.14 When Sysprepping a Windows 8 or Windows 8.1 PC

You want to Sysprep a Windows 8 or 8.1 workstation.


Sysprep  on Windows 8 and 8.1 often fails with a 3.14 error. This is due to the fact that Windows runs scheduled maintenance tasks exactly one hour after the operating system’s initial setup, and they prevent Sysprep from executing.

  1. Open a Command Prompt
  2. Run the command:
    C:> Schtasks.exe /change /disable /tn “MicrosoftWindowsAppxDeploymentClientPre-staged app cleanup

You should be able to run Sysprep as normal at this point.
