This page answers the question: How do I apply a patch to a module?
Much of the existing patching documentation on how to apply a patch (see links below) is extremely cryptic and assumes more technical knowledge than some aspiring, but worthy patchers have.
But even those with somewhat lesser technical know-how may want (or need) to apply a module patch from time to time. For instance, there is an important feature that has been developed for your module, but it is still not available in an official release. Or, you have reported a bug in the module, and the module maintainer has asked you to test a patch that fixes it.
This how-to provides a detailed step-by-step guide to applying patches to contributed modules. It is designed for first-time patchers and/or less technical folks who have the need to apply a patch. The how-to specifically relates to applying patches on Windows machines, but the basic information and steps may be helpful for others. It is also written for a localhost (i.e., a development environment, and the particular directory structure follows XAMPP's naming) configuration, but the same steps would apply to a hosted environment as well, if it is a Windows environment. You'll just need to switch the location where some of the steps are executed.
