Default Behavior

The Pdc service is a kernel device driver. In Windows 8 it is being loaded by Boot Loader before Kernel initialization. If Pdc fails to load or initialize, the error details should be automatically logged. Then Windows 8 is restarting the PC and attempting to use the Last Known Good configuration. If the Last Known Good configuration isn't working properly, Windows 8 startup ends with a Stop error. If you disable the pdc service, Windows 8 will fail to start.

Restore Default Startup Configuration for Pdc

1. Run the Command Prompt as an administrator.

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

sc config pdc start= boot
sc start pdc

3. Close the command window and restart the computer.

The pdc service is using the pdc.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.
