First, disable cdp user service Open Regedit and got to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDPUserSvc
The value Start defines the start value of the service. The values are defined as:
2 Automatic
3 Manual
4 Deactivated
If you set the value to 4, the service is disabled. However, Windows 10 seems to reset this value from time to time. In addition, a deactivated service causes certain functions to be missing in Windows 10. At German forum administrator.de, someone has even written a batch program in this forum post to deactivate the relevant services. Also Woody Leonhard mentioned at ComputerWorld a script that Glenn Turner has put together to disables the CDPSvc and CDPUserSvc services. It’s quite adventurous what you have to do as an administrator to keep your systems up and running.
