Explanation:

For Question 4, in debugging software, the register window is typically accessible in debug mode. Compiling and linking are different phases from debugging, and the program not running doesn't specifically relate to opening the register window. For Question 5, hovering the mouse over the register name or viewing in the register window are common ways to see register values. The spy - window is not the typical way for this.

Answer:

Question 4: In debug mode
Question 5: Hovering the mouse over the register name or viewing the register inside the register window.
