With its new "Russian Doll" model of linearly progressing features, Microsoft thinks its new lineup of six editions will meet a wide range of consumer usage models. All versions of Windows 7 include Internet Explorer 8 and DirectX 11, as well as improved multi-core processing.

With improved boot times and overall system responsiveness through all versions, Microsoft believes these engineering investments will allow small netbook PCs to run any version of Windows 7, and allow customers the flexibility to purchase a system which meets their needs. It has also improved support and optimizations for Solid State Drives, targeting both netbooks and notebooks.

Expanded features were requested by corporations for the Enterprise Edition. Virtual Desktop Infrastructure allows Windows 7 to be run as a virtual machine. Branch Cache is a file caching option for branch offices of large corporations, designed to reduce access times to centrally managed files. DirectAccess is designed for corporate networks based on Windows Server 2008 R2, which is the server version of Windows 7. AppLocker is a centrally managed, rule-based group policy program for specifying which applications can run. Enterprise Search was designed as a highly secure, manageable, server-based search system. It enables users to search remote document repositories, SharePoint sites, and Web applications.
