Description 

Address Status (at the top of the window) 

Displays the effective address (when available) and the value stored at that address. For example, if you select an address containing an expression in brackets such as [eax+edi*4-0x0F], the location in memory being referenced and its current value is displayed.
The current thread ID is also displayed.  

Disassembly pane (upper left side) 

Displays the address, the hexadecimal representation of the machine code instructions (opcodes), and the assembly instructions for each line of source code. The address is the offset into the disassembled method.
If you are debugging managed code, the assembly instructions correspond to the native code created by the JIT compiler. The Microsoft Intermediate Language (MSIL) created by the compiler is also displayed. Note that there is not a one-to-one relationship between the native code instructions and the MSIL instructions. You can not step into or set breakpoints on the MSIL instructions.
If debug information is available, the debugger displays the source code that corresponds to the assembly instructions.
A right arrow () to the left of an address indicates the current execution point.
When the current instruction is a transfer instruction (for example, call or jmp), either an up or down arrow after the instruction indicates the target direction for the transfer instruction. For example, if the target is located before the current instruction, an up arrow is displayed. If the target is after the current instruction, a down arrow is displayed.
For conditional transfer instructions (for example, jz or jle), an arrow is displayed only if the condition is true. For conditional set instructions (for example, seta or setz), a left arrow is displayed if the condition is true.  

Register pane (upper middle pane ) 

Displays the contents of the CPU registers of the 80386 and greater processors. These registers consist of eight 32-bit general purpose registers and the 32-bit program counter (EIP).
When debugging Win32 code, the flags (EFL) register and the six segment registers are also displayed.
After you execute an instruction, any registers that have changed value since the program was last paused are highlighted in red.  

Memory Dump pane (lower left side) 

Displayed only for unmanaged code. Displays the raw values contained in addressable areas of your program. The pane displays the memory addresses, the current values in memory, and an ASCII representation of the values in memory. The leftmost part of each line shows the starting address of the line. Following the address listing is an 8-byte hexadecimal listing of the values contained at that location in memory. Each byte in memory is represented by two hexadecimal digits. Following the hexadecimal display is an ASCII display of the memory. Non-printable values are represented with a period.
Press CTRL+LEFT ARROW or CTRL+RIGHT ARROW to shift the starting point of the display up or down one byte.  

Flags pane (upper right side) 

Displayed only for unmanaged code. Displays the current state of the flags and information bits contained in the 32-bit register EFL. After you execute an instruction, the Flags pane highlights in red any flags that have changed value since the program was last paused.
The processor uses the bits in this register to control certain operations and indicate the state of the processor after it executes certain instructions.
Pass the mouse over a flag to display the flag name.  

Machine Stack pane (lower right side) 

Displayed only for unmanaged code. Displays the raw values contained in the your program stack. The pane has three sections: the memory addresses, the current values on the stack, and an ASCII representation of the stack values. A green arrow indicates the value at the top of the call stack.
