Hardware that runs Windows Vista well will run Windows 7 well

Few Changes: Focus on quality and reliability improvements

Windows 7 Builds on Windows Vista

Deep Changes: New models for security, drivers, deployment, and networking

Solid Foundation

MemoryReference set, graphics

Disk I/ORegistry reads, indexer

Rich Metadata

Cleaner navigation

Easy Previews

Powerful Instant SearchArrangement Views

Federated Search

Libraries

Libraries

Supporting and Using LibrariesYour application should:

Support open and save in librariesSelect and consume library contentsStay in sync with library locations

e.g. Windows Media Player

The Windows 7 enables this via:Common File Dialog

Native: IFileDialogManaged: System.Windows.Forms.FileDialog

Shell abstractions (i.e. IShellFolder)New Library API to manage libraries

Be Library Aware

Federated SearchConsistent experience across providers
