Hi all,
When I I am typing in an edit field, let's say on social media, NVDA
loses focus and moves to Cortana.
I never use that Windows application and wonder if it is possible to
get rid of it and if it is would it help the issue of losing focus?

Nevzat,

That's not typical behavior I've encountered before.  You used to be able to
fully disable Cortana, and I had for a very long time.  As of Version 20H2
of Windows 10 she has reappeared on the taskbar, but remained silent for
me.  I just got rid of the button using the context menu for the Taskbar.

Bring up the context menu for the Taskbar and make sure that the "Show
Cortana" option is unchecked.  If it's not present to try to draw focus, and
you don't use Cortana, that might very well do the trick.
