i have a machine with two Win 10. One is over an SDD and the other on a ordinary HDD.

I have an issue with Cortana in the second Win 10... I press "WIN" and write something but nothing work... only White tab. While in the other Win 10 on the SDD Cortana works perfectly.

To be sincere, sometimes, Cortana works on the second but only for example one time over five. Sometimes I disconnect and reconnect the user and works but for example today I tried this but without luck.

I also have this issues when I go in Safe mode in both Wins.

What I can check in the second Win 10 in order to make Cortana work?
