Updated now to version .1172 over .1171 and everything seems to work perfectly (even my jumplist survived the update and is still working as is).
I would'nt dare making a clean install.
Thanks Bill, having some strange code in there to keep it for me. :?
Icons on desktop: first try, all 40 assambled on desktop with the correct icon and vanished in the dark when deselecting. So for me this build ist perfect (except for the "MISSING JUMPLIST").
Thanks jv16 and the team! 8)
