I followed the steps listed by MC10 in this link Can I completely disable Cortana on Windows 10?
But then I realized it disables being able to search using the start menu and I want to re-enable Cortana. I tried deleting the .bak from the file folder, but I can't because Windows created a new identical folder. I tried removing the new folder and removing .bak, restart, no luck and then I also just got rid of the old .bak folder, restart no luck.
How can I get Cortana working again?
