What is a DWORD 64-bit?
DWORD stands for “Double word,” and QWORD stands for “Quad word.” These illustrate the length of the words and are not associated with the system architecture at all. A standard WORD bit-length is 16 bits. Therefore, a double WORD bit-length is 32 bits, and a quad WORD bit-length is 64 bits.

What is DWORD 32-bit and QWORD 64 bit?
DWORD (32-bit) Values & QWORD (64-bit) Values This means that you can have both types of registry values on both 32-bit and 64-bit operating systems. In this context, a “word” means 16 bits. DWORD, then, means “double-word,” or 32 bits (16 X 2). Following this logic, QWORD means “quad-word,” or 64 bits (16 X 4).
How do I create a DWORD?
