Windows 10: My Cortana search is not working

When I say "Hey Cortana" and pose a question or command it works just fine --but I don't like to use the microphone, I like to type in my question and this has always worked. Recently this function quit working and now I get error message that says "preview is not available at this time" and then it tells me to open an app?? I don't know what this means, I have not done any updates or downloads. Please advise

:)

 

Cortana search filter list


I have a lot of space for display content in Cortana search list, and 80% of it not used because Cortana sorting items by types.
How disable all filters and make visible all suggested content?

 

Cortana search not working AT ALL

Cortana has not worked since I took the laptop out of the box. There were no changes made to the PC. I will try creating a new admin account as suggested by the link above and will let you know if that still does not work. I have tried all of the other
steps listed in that article.

 

Cortana and Search Box no longer working after windows refresh

Hi Nachappa,

Thanks for your quick response. To answer your questions:

• Per your suggestion, I tried Safe Mode. The problems still existed in Safe Mode. As a side note - I realized in the process that my power button has disappeared from the sign in screen, so I had to activate Safe Mode from Settings. Not sure if that is
  related to the Cortana issue or not.
• I ran sfc/scannow. It came back that there were some corrupted files, but they could not be fixed. I restarted the computer, and the search bar/Cortana still wouldn't work.
• I ran all three Dism prompts and they all came back as having successfully completed. I restarted the computer, and the search bar/Cortana still wouldn't work.

What would you suggest as a next step?

Thanks,

Maria
