I had nearly forgotten about that! Nice find from last July :)
I used this tip since on XP, and I hadn't yet used it under 7, but Pode happened to ask about this in IRC, so I dug a bit into the forum.
Hapilly Ashley hasn't the word "registry" a lot in his posts, so it was quite easy to find ^^
It's indeed a useful tip that deserve to be reminded/broadcasted.
