Step-1: Launch Registry Editor and go to the below-given path.


Step-2: Create a new registry DWORD DisableAuthRetry. Set its Value as 1 and save the changes.

Windows 10 KB4338827  resolves the problem where after a user logs on, not all network printers are connected. The following path in the Registry displays the correct network printers for the affected user.
