Security and reliability: Every feature in this category is available in all editions: Action Center, Resource Monitor, Windows Update, Windows Defender, Windows Firewall, and Parental Controls. The significantly less annoying update to User Account Control works the same in Starter as it does in Ultimate. Two huge changes in this category show that Microsoft really was listening to its critics: The Backup program provides full functionality in every edition, allowing you to create a system image and do file backups to an external hard drive or rewritable media (in Vista, system image backups were possible only in Business edition). In addition, the Previous Versions feature now works in all editions. This feature allows you to recover earlier versions of a file from automatic system restore points (Apple has a similar feature, slicker but less powerful, in Time Machine). Oh, and you can make a System Repair Disc any time with any edition.
