In Windows 10, there is a delay to improve startup after you log on so that startup programs don’t open all at once. When Windows 10 is started, it delays the loading of apps from the Startup folder. You can reduce this startup delay for desktop apps with a simple Registry tweak.
Windows 10 comes with a feature “Fast Startup” enabled by default. It speeds up the boot process. Fast Startup makes Windows boot very fast.It depends on hibernation. You can disable full hibernation to save disk space but keep Fast Startup enabled in Windows 10.
