since I got some requests regarding this issue, I will post it for future reference:
Upgrading to Windows 10 messes up the "Intel Depth Camera Manager (DCM)" service.
Perform the following steps:
- open the "Programs and Features" from the Windows Control Panel
- look for the "Intel RealSense Depth Camera Manager F200" and uninstall it
- install the new one (currently 1.4) from https://software.intel.com/en-us/intel- ... k/download
