Cannot connect my Nexus 5X to Windows 10 PC
Okay I finally found something which helped me.

The Media Feature Pack for Windows 10 N &amp; KN (all editions) alias KB-3010081 is for the first version of Windows 10. 

But for the Windows 10 with the big update we had a few time ago, there is an update which supersedes the KB-3010081.
This is the KB-3099229 : https://support.microsoft.com/en-us/kb/3099229.
 Download : https://www.microsoft.com/en-us/download/details.aspx?id=49919

After all my attempts to resolve my problem, this is the thing which did it for me.

I Hope it will helps.

Best regards,
