Have a look…
Sinking the Sea….
Originally a version of Windows named Blackcomb was planned as the successor of Windows Vista.
Developers wished to give emphasis on searching and querying data and an advanced storage system called WinFS to enable such scenarios.
Blackcomb was renamed to Vienna in 2006 and again to Windows 7 in 2007.
Windows 7 was planned to be designed as “user-centric” and it also focus on performance and improvements. To make it practical, the company uses new tracing tools to measure the performance of the operating system in many areas.
What is WinFS?
WinFS (Windows Future Storage) is the code name for the data storage and management system developed by Microsoft.
WinFS includes relational databases for storage of information and allows any type of information to be stored on it, provided there is a well-defined schema for the type.
Individual data items are related together by relationships, which are either inferred by the system or explicitly specified by the user.
As the data has a well-defined schema, any application can reuse the data.
Related data can be effectively stored and retrieved as relationships are present for each data type.
Step to Windows 7—Flaws of Vista
One of the highly criticized feature of Windows Vista is the User Access Control, which prompts up a dialog box seeking user’s permission to continue or stop whenever a system-level change is made.
Even the default user account (Administrator account) which will be created during installation could not bypass the UAC.
Only two features were present for UAC in Windows Vista. Turn on UAC or Turn off UAC so that the user could not have much control.

Windows 7 system requirements
User-Friendly GUI
Jump Lists
Jump Lists provide users with quick access to a mini-Start menu containing lists of pictures, music, word documents or links that they use most frequently.
Taskbar Peek
This feature applies the Aero Peek technology to taskbar thumbnails.
Aero Snap
Maneuvering between windows is a pain, and comparing the content of two windows side by side requires awkward resizing that never quite works.
UAC
Four Options for notifications from always being notified to never being notified, including only getting warnings when software is installed.
Bit locker
BitLocker To Go Protection. BitLocker® has become a saving grace when it
comes to increased laptop security. Windows 7 has taken security even farther
with its BitLocker To GoTM feature, which allows you to encrypt removable USB
devices and external disks. To enable BitLocker or BitLocker To Go, right click the
drive in Windows Explorer and select “Turn on BitLocker…” This can also be
managed centrally via Group Policy, so IT administrators can require the USB
drive be encrypted before files can be written to it.
IE 8
Instant Search – offers suggestions and visual representations of search results
Accelerators - help you quickly perform your everyday browsing tasks without navigating to other websites
Web slices – allows you to subscribe to a specific part of a web page instead of the whole page
