Well, I have made an unattended Vista sp1 but I have a small problem. The thumbnails of images in explorer show photos 1 second and then hide all previews (see capture below). Capture: Before that I have modified Registry Values for the unattended but I think all it's ok, I don't know if the error is in the reg file. I put the reg, if you find the error, comunicate me please. I want to change or activate thumbnails from registry (for the unattended installation). The Vista is the sp1 normal without changes + the reg file tweaks. http://rapidshare.com/files/114383818/Setup.zip.html http://www.megaupload.com/?d=JHT5AIHG Thanks for all
