It looks like Microsoft is making Cortana a central focus to many of its search functions including showing up on the lock screen. It will not only be more prominent but will also be much harder to get rid of “her”.
With the Windows 10 Anniversary Update, the search box is now Cortana. Customers can expect the same great search experience powered by Bing and Microsoft Edge with the added benefit of Cortana’s personality.
If your system is on a Windows Domain Network your IT Department can control this through group policies but we don’t have a simple and quick method of shutting “her’' down.
Another “feature” that is baked in is the inability for consumers to control Windows 10 updates. Your going to have to suffer through them.
The spokesperson suggested that there are some Cortana tweaks that Windows 10 consumer users could do, if wanted:
We know consumers want choice and we make it easy to customize Cortana’s personalization or opt-out of Cortana’s suite of personalized services. Cortana works best when you sign in, but if you choose not to, you can still use her to chat, search the web and your Windows device. If you like, you can also easily hide Cortana and the search box in the taskbar altogether.
Cortana is also going to hold a prominent role in educational environments as well.
For our education editions, Microsoft is committed to an experience free from sponsored content by default. Within Cortana, Microsoft could not guarantee that sponsored content would not appear as part of the online search experience.
Microsoft is working on creating a future Cortana service that has an "education-appropriate experience."
