Do typical Home edition users even know what an image is? My take for John Q. User: let Windows take care of Windows--do what it tells you (update, configure backup, answer the firewall popups deliberately, install a vetted AV suite) and you (and your friends and neighbours) will be fine. You will have system images, restore points, incremental backups, pre-boot recovery options, malware protection, firewall protection, vulnerability protection (through updates--first line of defence), and you don't have to fiddle with it after initial setup! Microsoft shouldn't be faulted for this--in fact, considering what the OS costs, it should have these things (not not frilly fluff like mediocre media players). Ounce of prevention: 90%+ Client PC cleanups/disasters I've dealt with could have been avoided by merely not bucking the system (no pun intended), even with UAC off (by all means disable it if it gets on your nerves).
