How to convert pdf file to ms word?

Every program you use has a tools menu someplace. You should find it and click every item to see what the program can do for you. Windows has an icon called "Start" and the tools menu is called "Control Panel". You don't have to memorize everything, just remember that it's there. Then you can claim to know how to operate a computer at the beginner level.

I loaded a .pdf file and clicked "File/Save" and one of the options is to save in Word format. I don't know about Word, but I suspect it can load a .pdf file just fine.
