When specifying a path to a file containing spaces in the Windows Registry, quotation marks must be used in order for the OS to interpret the path correctly. If quotation marks are not used, the OS will treat the file path up until the first encountered space as the full path. For example, C:\Program Files\Directory\Filename will cause Windows to execute C:\Program if such an executable exists, passing the "Files\Directory\Filename" portion of the path as an arugment to the program.
