Solved Intel(R) Content Protection HDCP Service error

I discover after a system controle that the service "Intel(R) Content Protection HDCP Service" can not be started it gives error code 0x80004005.
What is this service doing and why can't it be started ?

Quoting Itel:-

High-bandwidth Digital Content Protection (HDCP)​

High-bandwidth Digital Content Protection (HDCP) is a form of digital rights protection to create a secure connection between the source to the display.
Intel created the original technology, which is licensed by the Digital Content Protection LLC group. HDCP is a copy protection method where the audio/video stream is encrypted between the transmitter and the receiver, protecting it against illegal copying.

Thanks for the info, now I no where to look, I don't use the internal Intel grapics but my external videocard, so I did a test I connected a monitor on the internal card and switch the internal card on in the bios, and yes the HDPC service can be started with no error. So no problem with my system, so learned something again
