Winload.exe (Windows Boot Loader) is a small piece of software, a so-called system loader, that is started by BOOTMGR, the boot manager used in the Windows 11, Windows 10, Windows 8, Windows 7 and Windows Vista operating systems.
Winload.exe loads essential device drivers and ntoskrnl.exe, an essential part of Windows.
In older Windows operating systems, such as Windows XP, ntoskrnl.exe is loaded by NTLDR, which also serves as a startup manager.
