What is the reduced functionality mode in Windows Vista?
Reduced functionality occurs when a Windows Vista system fails to activate as required within 30 days after installation. A Software Licensing dialog box will appear after logon, but there will be no Start menu, no desktop icons, and no personalized wallpaper or desktop background. Users who need to obtain a valid product key or need more information on how to activate Windows can click the “Learn more online” link in the Software Licensing dialog box to go online and get the latest options and information available from Microsoft. In reduced functionality, the default web browser will function so that users can go online for troubleshooting, but Windows will log off after one hour without prompting. Unsaved work must be saved prior to the one-hour automatic logoff or it will be lost. To access documents, applications and other data stored locally, users can also start the computer in safe mode.
