To go to c:\emacs, type "chdir c:\emacs".
Use "dir" to see the contents of your c:\emacs directory. It should contain the files emacs.gz, gunzip.exe, and tar.exe. However, it is possible that your filenames will be slightly different---e.g., they have extra suffixes. In that case, use the names that appear in your directory in the next step.
Note: If you installed scheme in some location other than the default folder, you'll need to alter the line beginning with setq scheme-program-name. Notice that two files (with the same path) are indicated here. You'll need to change both the paths. You can find the correct path by looking in petite.bat in your c:\Windows\ folder. Note the forward slashes.
