Default Behavior

The Sdbus service is a kernel device driver. In Windows 8 it will not be started until the user starts it. If Sdbus fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the sdbus service hasn't been started.

Restore Default Startup Configuration for Sdbus

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_sdbus_Service_Startup.cmd file to a local storage device.

The sdbus service is using the sdbus.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
