    Default Windows 10 update kb4462933

    Hi All,

    Good evening.

    I noticed that after I did a Windows update (just performing OS maintenance/cleanup) my SCSI drive disappeared, I Looked through the logs and found the following:

    Disc Soft Lite Bus Service
    "C:\Program Files\DAEMON Tools Lite\DiscSoftBusServiceLite.exe"
    The description for Event ID 0 from source Disc Soft Lite Bus Service cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

    If the event originated on another computer, the display information had to be saved with the event.

    The following information was included with the event:

    Service started/resumed

    Even after I forced the service to restart, uninstalled Daemon tools and re-installed it, cleared all data of Daemon Tools (c:\users.... | program files....) restarting after the each step the SCSI drive still never appeared and I got the the error the application.

    'daemon tools insufficient resources to create target connection'

    So I formatted my NVME drive, disconnected all other HDDs and DVD drives and did a fresh install on Windows 10, did not installed any motherboard drivers, graphic drivers, only Daemon tools....the SCSI drive then appeared!

    I then restarted the PC and the drive was still present so I then did the windows update and these KBs were installed

    The SCSI drive then disappeared, again, so I removed the KB, kb4462933 and after a restart of the OS the SCSI came back and is working correctly.

    I'm not sure if this would be classed as a bug however, I needed to make someone aware just in case there's a better fix than removing a Windows update!

    Thank you
