Don't they have a number we can call. This is all BS. When you buy something it should work as advertised, why are we messing with files etc etc. :s
I have a DK2 and also had the same problem after the last update of Windows 10. Simply, the sensor camera stopped working and turned off the blue light (which was always lit) and the games did not run.I tried the suggestions here, but for me it did not work!By chance, I found the folder "C: \ Program Files \ Oculus VR Runtime Drivers \ Drivers" and there was three subfolders: DK2Sensor, Monitor and Rift Sensor.So, I went into Device Manager and sent to update the Rift DK2 Sensor driver. However, I chose not to update automatically (to search the driver also on the Internet), but get the drive on your computer and choose the folder that I quoted above "C: \ Program Files \ Oculus VR Runtime Drivers \ Drivers" and Windows updated the driver and the Rift sensor returned to work.PS .: - Before, I had tried to update the driver with automatic search, but did not work; since Windows reports that "the best driver is already installed."- Also, I tried to only choose the subfolder "... Drivers \ DK2Sensor" but did not work.I do not know if these folders also exist in CV1 and which name appears in the "Device Manager" Windows 10 for the camera sensor rift; but for the DK2 was:PROBLEM SOLVED!
