A long time ago, I ran some scripts from the web to increase the privacy of my Windows 10 installation. Among other things it disabled Cortana. Except for multiple error messages in the event viewer saying that DCOM could not start Cortana (a good thing in my opinion) everything else seems to work correctly.
That was with build 1903.
Since then, every attempt to upgrade to build 1909 resulted in the search box being disabled in explorer windows, and none of the solutions I could find was able to fix it, and I ended up reverting to 1903.
Is there a way to update to a more recent version without killing the search functionality in explorer?
