Resetting a Windows 7 PC can be messy. Depending on which refresh mechanism you use, such as a third-party imaging program or a clean reinstall from a Windows DVD, the experience often varies from one PC to another. Windows 8 changes that by applying a uniform, push-button solution to starting over. You have the option of "resetting" your PC, which deletes all personal data, apps, and settings before reinstalling Windows; or "refreshing" your system, which reinstalls Windows but retains your personal information.
