Instead of RUN/etc., do Start/Programs/Accessories/
Command Prompt, then enter "ipconfig ENTER".
To speed up getting the Command Prompt window in
the future, do Start/Programs/Accessories, and right click
on Command Prompt and drag-'n-drop it to the top portion
of the Start menu and select Copy Here. Thereafter, you
can run Command Prompt by selecting it from the initial
Start menu.
