When I first installed Windows 10, Cortana was working

 

I didn’t jump into using it right away but later came back to find that it no longer functioned at all.

“Are you mad bro” comes to mind.

 

I would like to avoid a clean install to get this working but seem that this may be the only option until I can understand what I changed or what has updated to cause this.

I am using the Windows 10 Preview build 10041

 

Could it be Chrome?  For now its a unknown.
