What is Regopenkeyexw?
RegOpenKeyEx opens a key in the Windows registry. The handle it gives must be used when you read to or write from any values under that key.

What is Regqueryvalueexw?
h header defines RegQueryValueEx as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant.
What is KEY_WOW64_32KEY?
KEY_WOW64_32KEY on a 64-bit OS means that the registry access, no matter if it’s a 32 or 64 bit process, will access the 32 bit registry view. Neither of them have any effect on a 32-bit OS.
What is Hkey_current_user?
HKEY_CURRENT_USER. Contains the root of the configuration information for the user who is currently logged on. The user’s folders, screen colors, and Control Panel settings are stored here. This information is associated with the user’s profile.

What is a REG_DWORD?
REG_DWORD – This type represents the data by a four byte number and is commonly used for boolean values, such as “0” is disabled and “1” is enabled.
What is DWORD QWORD?
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 WOW64 mode?
WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run seamlessly on 64-bit Windows. This allows for 32-bit (x86) Windows applications to run seamlessly in 64-bit (x64) Windows, as well as for 32-bit (x86) and 32-bit (ARM) Windows applications to run seamlessly in 64-bit (ARM64) Windows.
What is QWORD 64 bit value?
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).
What is Reg_sz and REG_DWORD?
REG_SZ. Entries of type REG_SZ are fixed-length text strings. Most of the entries that use this type are either Boolean or have short text string values. This data type is common and probably arises almost as frequently as the REG_DWORD type.
What is a 16 bit word?
A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
What is HKEY_LOCAL_MACHINE Sam?
SAM = Security Accounts Manager. SAM contains local user account and local group membership information, including their passwords. Password information and privileges for domain users and groups are stored in Active Directory.
