Hello, I'm new here, and I'm having a slight problem with following this tutorial. I mount the .wim and follow all specified directions, remove and add what I care to do, etc. When I am finished and choose to unmount it does not do anything. Perhaps I am not patient enough (I've waited at least five minutes each time) for it to do its task, but I don't make too many changes and your tutorial says it should not take long. Thanks in advance.
