Clearing memory is a common task, whether manually done by the programmer or added by something like a compiler. In this video, we’ll explore how to clear memory using a few x86 instructions.

How to build the sample program with Visual Studio:
First, assemble with NASM:
nasm -f win32 zero_mem_xor.asm -o zero_mem_xor.obj

Then link with MSVC:
link /SUBSYSTEM:WINDOWS /ENTRY:start zero_mem_xor.obj kernel32.lib /OUT:zero_mem.exe /MACHINE:X86
