If I back up a drive to an image, will all of my passwords for windows accounts, internet websites, cookies, browser history, etc. be saved in that image as well? I'd like to create an image of my entire system plus settings and tweaks, but not include web browser information or any other sensitive data.
Well you can back up excluding these settings, but an image, typically means you're copying block level data and which doesn't differentiate between files and settings.
Well, this is not strictly true on the enterprise level with granular image recoveries and such, but with consumer OS you'd need to do a backup not an image.
