11.1.  Starting GHC on Windows platforms

The installer that installs GHC on Win32 also sets up the file-suffix associations for ".hs" and ".lhs" files so that double-clicking them starts ghci.

Be aware of that ghc and ghci do require filenames containing spaces to be escaped using quotes: 

  c:\ghc\bin\ghci "c:\\Program Files\\Haskell\\Project.hs"

If the quotes are left off in the above command, ghci will interpret the filename as two, "c:\\Program" and "Files\\Haskell\\Project.hs".
