ntoskrnl.exe (short for Windows NT operating system kernel executable), also known as the kernel image, contains the kernel and executive layers of the Microsoft Windows NT kernel, and is responsible for hardware abstraction, process handling, and memory management.
Kernel Patch Protection is the technology that enforces these restrictions. It works by periodically checking to make sure that protected system structures in the kernel have not been modified. If a modification is detected, then Windows will initiate a bug check and shut down the system, [6] [8] with a blue screen and/or reboot. The ...
This is not a crash screen, however; upon crashing, Windows 1.0 would simply lock up or exit to DOS. This behavior is also present in Windows 2.0 and Windows 2.1 . Windows 3.0 uses a text-mode screen for displaying important system messages, usually from digital device drivers in 386 Enhanced Mode or other situations where a program could not run.
A Yellow Screen of Death occurs when an ASP.NET web app finds a problem and crashes. [8] [self-published source?] A kernel panic is the Unix equivalent of Microsoft's Blue Screen of Death. It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continuing the operation may risk escalating ...
The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process.
A crash dump file can also be created, which is a binary file that a programmer can load into a debugger. Dr. Watson can be made to generate more exacting information for debugging purposes if the appropriate symbol files are installed and the symbol search path (environment variable) is set.
The bootsect.exe utility program in the Windows PE tools has options /nt52 (NTLDR) and /nt60 (Vista and up) to store a NTLDR or Vista boot record in the first sector of a specified partition. [1] The command can be used for FAT and NTFS based file systems .
The Windows Boot Manager invokes winload.exe—the operating system boot loader—to load the operating system kernel executive (ntoskrnl.exe) and core device drivers. In that respect, winload.exe is functionally equivalent to the operating system loader function of NTLDR in prior versions of Windows NT.
