Ok, now I'm about to do you something of a favor if you will just listen and take a bit of advice...
1) Get a book on Windows (It's a link, click on it)... Study well, learn how to really operate your own system. Pay special attention to the parts about the Windows filesystem and command line, you'll need to understand both before you start programming.
2) After you finish the windows book. Get yourself a good compiler and IDE... I generally recommend Pelles C (yes that's a link, click on it) since it is very well documented, comes with everything you need and is free. First thing you do is read the help file... get familiar with it's contents and especially the parts about using the integrated environment.
3) After you get familiar with Pelles C, get a book on C programming (Yep, another link to click on). Go through it page by page, type up and compile all the examples and work through all the exercises. Play with the code as you study the text, move on to the next page only when you are confident you've understood the current one.
Yeah that's a lot of stuff... but, when you're done, you'll be glad you did it!
