Windows Vista Toilet Paper
This is in fact the function guide of Vista as a sales promotion good of Windows Vista Ultimate SP1 edition, which was put on the market on Mar 15. Along with the toilet paper, the shop (T-zone PC DIY) in Akibara, Tokyo would also present bottles of bath oil (the right one in the first photo).
What a good use for Windows Vista. 😀
