Hello & welcome to Seven Forums.
1: Auto log on to your user account
2: Select a power plan
& Change power plan settings
3: not really my area of expertise, sorry
4: Driver - install add printer wizard
or you might try installing the Canon software in compatibility mode.
5: How long does it take to boot up? If it's around a minute or so, it's perfectly normal.
6: There are 2 versions installed, one 32(86)bit and the other 64bit; because you have 64bit Windows, as I gather from your specs.
I hope this will help you out, but if you have any more problems or questions, don't hesitate to ask.
