I can do you one better. Several years ago, I was working on a specific driver issue with deploying Windows XP on a couple hundred PC's and needed help with making my image more universal with some driver packs. Something was breaking and I wasn't sure what I did wrong.

Looked up in the forums for these driver packs and was trying to get some answers and luckily there were a few threads about it and I looked through them. Saw some rather terse descriptions of how to do it, but finally found a really detailed guide.

Was great to find not only what I needed, but something that gave a well written step by step of the whole process. Not until I finished reading the guide and saw the signature did I realize it was my guide I had written a few years earlier and hadn't thought of in a long time.
