Default Behavior
Pdc is a kernel driver. In Windows 11 it starts by the operating system Boot Loader before the Kernel initialization, as a part of the driver stack. If Pdc fails to start, Windows 11 tries to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration can't be used, Windows 11 startup process halts with a Stop error. If you disable or delete the pdc service, Windows 11 won't start.
Restore Default Startup Configuration of Pdc
1. Run the Command Prompt as an administrator.
2. Copy the commands below, paste them into the command window and press ENTER:

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 C:\Windows\system32\drivers directory. If the file is removed or corrupted, read this article to restore its original version from Windows 11 installation media.
