Windows 10 and 11 optimize the startup sequence to ensure a balance between performance and usability, leveraging a combination of software and hardware advancements. Both operating systems use a prioritized approach to load essential system processes, services, and user applications efficiently. They utilize the Unified Extensible Firmware Interface (UEFI) for faster initialization of hardware components, while Fast Startup, a hybrid of shutdown and hibernation, allows quicker boot times by saving a system state to disk. Additionally, Windows employs a feature called Startup Impact Assessment, which categorizes applications into "High," "Medium," or "Low" impact to delay non-critical processes until after the desktop is usable. Tools like Task Manager and Startup Settings let users control which programs launch at boot, helping to streamline performance further. These mechanisms collectively ensure that the system is ready for use quickly while preserving user control over startup priorities.
