WinXP Pro SP2, Pentium 4, 1.8GHz computer.

Simply add a new module to the project and paste all the code into it. Then call the function sGetXPCDKey() from the application: eg
msgbox sGetXPCDKey()

In the future suggest that you enclose the code inside code tags to make it easier to interpret here.
