While similar, Windows Search is independent of Cortana. A known bug with Windows Search is:

Failed to enumerate user sessions to generate filter groups.

This error is more common in recently installed versions of Windows 10. Basically on systems where Windows Search has not started yet. While in some situations it only stops searching for Windows, in others it abruptly restarts the system, making it a problem.

The causes could be a problem with the registry, Windows Search was not initialized correctly, and the SYSTEM account was not added to DCOM security.

Try the following solutions one by one to fix the problem:

3] The right mouse button in the service and select Property.

3] In the right pane, right-click the item SetupCompletedSuccessfully. Please select Modify.

Finally reboot the system

Solution 3] Add SYSTEM to DCOM Security

1] Press Win + R to open the Run window and type the command dcomcnfg. Press Enter to open the file Component Services window.

2] In the right pane, double click computer. Now, right click on My Computer and then click on Property.

4] Click INSERT and then in Advanced in the next window.

5] Click Find now and it will display a list of search results.

6] Select SYSTEM from the list and it will be added to the safety limits list.
