Thanks for the explanation, ilko, but the fact is that you did get enough information, you just didn't know how to use it. You act all confused about my mention of an ISO yet how else would I use an iso for these purposes other than to mount it? You then go further to act all confused about my mention of a sif file despite my added mention of winnt.exe. What other sif file could I mean that would have a relation to winnt.exe? If you don't know enough about a topic to answer the questions properly then don't bother. People will appreciate a well thought out answer more than a quick joke.
