Installing SP1 over a clean, full Vista x64 : At the final reboot i have a bsod and "Crah Dump" initialized. If i try to reboot again i have always this error message. Here there is no usefull info on the BSOD (only hexa-decimal numbers). I cant reproduce this BSOD for the moment because i'm tired to reinstall, reinstall again and again !! lol Another strange thing : After the SP1 update, some of my registry software (registry snap, registry search & replace) cannot work properly (they read Wow6432Node in an infinite loop) due these lines added by SP1 in the registry : If i delete them all my registry software work well again, and Vista work like a charm without these lines !!
