you can get the WFP lists with the following tool :

"§ Windows File Protection"

No, afaik, it's not possible. Only Microsoft decides what is "protected"
and what is not. Don't have time to check if things has changed right
now.
> The other option is to exclude System_State:\ from incrementals.
But be aware that you won't be abble do restore the machine itself,
(i mean the system/Windows part) as several critical Windows pieces
won't be in your backups.
