How old is your Mac?
Does it say iBook on the screen frame, or does it say MacBook on the screen frame or bottom? Mac OS 9.1 is a 15 year old operating system. If you mean Mac OS X 10.9.1 on a MacBook, you posted to the wrong forum.
Running Windows is possible, although the old iBook models only supported up to Windows XP or 2000.
MacBook models can all run Windows 7 or later.
To learn more about your options, see this tip:

Some alternative QMS software for the Mac is here:

Though if you have a Mac that can run Mac OS X 10.6 or later, you should look at the Mac App Store for Quality Management System software.
Do not download any system modification tools for the Mac. The only "maintenance" required for Mac OS X is a backup*:
