You have a point in this. However, this is not the most common case. I believe the majority of freelance users own their PCs and have administrator's privileges on them.
Of course they have admin privileges. But normally they are logged in as non-admins. So, your recipe will produce error messages only. That was the fact I wanted to point out.
We are in 2012. People who are logged in as an admin during their daily work are computer-illiterates and thus will not be able to benefit from your hints.
The solution in this case is very easy, just put your files within any folder under "My Documents" and it shall work.
You forgot the path problem I stated.
Let me put it clear:
Your proposed procedure is generally ok, but if one exactly follows the steps in your recipe, he or she will get into trouble. Most translators have never seen the Cmd window before. I don't think they will know anything about the necessary "cd .." command.
