No. User  files are untouched.

No because Microsoft have added a new feature 'EASY UPGRADE' and that will keep all user files backed up !

Have fun installing A **** Os ;P

Answer 3

Yes, nothing is gonna left coz when u r gonna install vista u r gonna have to format ur computer before so it's gonna erase everything, then u have to reinstall them. REMEMBER FIRST TRY TO GET A WIRELESS ADAPTER/CARD DRIVER and save it on ur flash drive or something if uhave only 1 computer then install vista and install the driver that u copied on ur flash drive ad then download other drivers like sound, graphice etc.. and then u r done :)
