Default Behavior

KSecDD is a kernel device driver. In Windows 10 it is starting by the operating system Boot Loader as a part of the driver stack for the boot volume. If KSecDD fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the KSecDD service, Windows 10 won't start.

Restore Default Startup Configuration for KSecDD

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config KSecDD start= boot
sc start KSecDD

3. Close the command window and restart the computer.

The KSecDD service is using the ksecdd.sys file that is located in the %WinDir%\System32\Drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
