How can you use Windows Scheduler to initiate an AHK macro?

I assume you're refering to "Scheduled Tasks" in Windows XP? If so, it is fairly simple.
Scheduled Tasks will run any program, if you have the proper rights. So all you need to do is to compile your AHK script into an EXE file (i.e. a program).
After that you only need to drag the EXE file into the Scheduled Tasks folder, and set the schedule. You'll have to make sure the user name and password are correct, or it won't run. They are under "Run as" and "set password".
