While similar, Windows search is independent from Cortana. A known error with Windows search is:
Enumerating user sessions to generate filter pools failed.
This error is more common with recently installed versions of Windows 10. Basically, with systems where Windows search hasn’t initiated yet. While in some situations, it simply halts Windows search, in others it restarts the system abruptly, thus making it a concern.
The causes could be an issue with the system’s registry, Windows search not being initialized correctly, and the SYSTEM account not being added to the DCOM security.
Try the following solutions one by one to resolve the issue:
