Yes you can.
Provided of course your machine has the facility to boot from the
requisite drive (I have the boot sequence on one set to
USB>CD>Floppy>HDD and the other one can be selected by pressing an 'f'
key at the right time) you can boot up Linux from a live CD/DVD and
have it run entirely in memory. It's not as fast as running it from a
HDD since it swaps bits of the program in and out of the memory as it
works but it doesn't use any of the HDD for its own purposes.

Yes you can.
My favourite flavour of Linux at the moment is Mint and I know from
experience that running a live CD of Mint, Ubuntu or Suse (other users
will vouch for other 'distros' I'm sure) that one of the items on the
new desktop will be called 'file system.' Thats your hard disk drive
and you can click through to any part of it. Windows hides files from
users and refuses you access to others but Linux isn't Windows and
will go where you tell it and show you what you want to see. (That
makes it powerful but also quite dangerous since there's nothing
stopping you hacking out whatever you want.) You can't launch Windows
programs but you can use Windows data files in the Linux equivalent
programs and you can modify them and save them back on the HDD again.
So a Word .doc or an Excel .xls can be modified by, say, Open Office,
then put back on the HDD to be opened again by Windows next time.

Yes it does.
Plus any changes you have deliberately introduced. One obvious use
might be to get rid of a pesky virus that boots itself into memory
each time you launch Windows and then replicates itself. A bit of
googling will tell you where to find the virus files so deleting them
when Windows (and the virus) is not in memory can get rid of the virus
once and for all.

Horses for courses and all that. If your sole interest is Windows
rescue then choose the cheapest magazine in WH Smith with a bootable
Linux disk on the cover. If you fancy playing about with it then pick
a disk with several versions. All live CDs allow the option of putting
Linux on your hard drive alongside Windows (dual boot) but you don't
have to do this.
