According to the BBC news site, it seems as if Vista is causing some people a bit of a headache because their broadband installation discs won't work with the new o.s. Poor things! I expect they are completely lost without a CD to do it for them.
I also fear for those who try the 16 steps laid out on the BT Vista help page to download new Vista-compatible Norton Internet Security software. "Copy the coupon code" "Follow the on-screen instructions." Sounds like the usual Norton recipe for disaster !!
