What is a dead critical process? Critical Process Dead The blue screen of death with error code 0x000000EF means that a critical system process on your computer has died. The process can be so critical that it can damage the hard drive, memory, or, in rare cases, even the processor.

The Windows 10 critical process stop code is easy to fix and the solutions can be various such as error etc.


You have encountered a rare thing – a blue death screen exclusive to Windows 8/10. BSoDs are historically very intimidating, but despite their name and appearance, most BSoDs are only temporary. This means that any errors you encounter can usually be corrected, although the process can be a bit painful. Earlier versions of Windows flashed around the error message needed to diagnose the incident with lines of code, but fortunately Windows 8/10 pushed the message into the background and you were kind enough to document it.


CRITICAL_PROCESS_DIED, whose error code is 0x000000EF, occurs when a process required for proper operation dies. Processes are like programs, but several processes can be used by a single program – and the processes interact directly with your processor, hence their name. The bad thing about this error is that it could be almost anything that is important for the operation of your computer: your hard drive, your main memory or, if you are particularly unhappy, your processor.
