|Acronis has a util that will allow you to make an imge. I have (and prefer) version-11; and it is still around although later versions have displaced it of course.|
The image will not work accross multiple platforms (different makes and specs of PC/laptop) due to how XP gathers and stores confiuration of the system to which it is installed. And naturally the image will have all of that for whichever system it was is taken... If you had another system that was more or less identical to that of the source of the image... then yes the image will transfer across; but you then have licensing issues to address?
