Final answer:
Following the startup of WINLOGON.EXE, Windows 10 initializes services and drivers configured for automatic start, and proceeds to load system and user processes, culminating in the login screen display.
Step-by-step explanation:
After NTOSKRNL.EXE starts the login file called WINLOGON.EXE during the Windows 10 boot process, the next step is to initialize the services and drivers that are configured to start automatically. Specifically, the Windows Service Control Manager starts critical services set to run at boot. Following this, system and user-initiated processes are loaded, leading up to the presentation of the login screen where users can enter their credentials.
