Windows 8 has two new features Reset an Refresh and both these features are designed as remedy to the whole OS reinstallation in case of virus, malware infection or random errors. It has become tradition among windows users to reinstall whole OS incase of unfixable errors but with Windows 8 things will change as the capability to revert Windows 8 to the state of fresh install has been added via reset and refresh feature.
In Windows 8 developer preview you can access system Reset & Refresh from Control panel or by pressing F8 key during boot process.
