MBRWizard is a Master Boot Record (MBR) management application for x86 and x86-64 based computers. As the use of disk imaging applications for backup and operating system deployment began to increase, as well as many users beginning to experiment with dual-booting Linux on existing Windows machines, key entries in the MBR were often changed or corrupted, rendering the machine unbootable.
CCleaner (/ ˈ s iː ˌ k l iː n ər /; originally meaning "Crap Cleaner"), [6] developed by Piriform Software, is a utility used to clean potentially unwanted files and invalid Windows Registry entries from a computer. It is one of the longest-established system cleaners, first launched in 2004. [7]
A "Cleanup" button on the "Startup" tab allows cleaning up invalid or deleted startup entries. In Windows Me and Windows XP versions, it can restore an individual file from the original Windows installation set. On Windows NT-based operating systems prior to Windows Vista, it can set various BOOT.INI switches.
The boot code in the VBR can assume that the BIOS has set up its data structures and interrupts and initialized the hardware. The code should not assume more than 32 KB of memory to be present for fail-safe operation; [1] if it needs more memory it should query INT 12h for it, since other pre-boot code (such as f.e. BIOS extension overlays, encryption systems, or remote bootstrap loaders) may ...
A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
Self-modifying code can involve overwriting existing instructions or generating new code at run time and transferring control to that code. Self-modification can be used as an alternative to the method of "flag setting" and conditional program branching, used primarily to reduce the number of times a condition needs to be tested.

[4] [nb 2] This signature indicates an IBM PC compatible boot code and is tested by most boot loaders residing in the System BIOS or the MBR before passing execution to the boot sector's boot code (but, e.g., not by the original IBM PC ROM-BIOS [16]). This signature does not indicate a particular file system or operating system.
