Windows OS history
•        Microsoft released a number of Windows operating system ranging from Windows xx, NT, server from 1985 till now. The latest is  Windows 7, released in 2009. Windows 8 isn’t yet released.



Microsoft Windows
•        Microsoft created the operating system, WINDOWS, in the mid-1980s.
 
•        They have a version of the operating system that is designed for the home user, and professional version, which is intended for the businesses
•        The versions differ in the depth of networking, security, and multimedia support
•        Windows is a proprietary software, which means that Microsoft has placed restriction on how people can use or copy the software
•        Windows comes preloaded on most of the PCs sold today, and can also be  purchased separately

Windows 7 Aims
 
- decrease Start up and shutdown times by 20 seconds
- go to sleep and Resume faster
- use up less memory
- pop ip search result faster
- Reconnect to your Wireless Network more quickly
- Recognize USB devices faster

Yes, a lesser-known aspect of the Windows 7 strategy is to appeal to SMBs (small and midsized businesses). Microsoft defines a small business as anywhere from five to 100 employees, and anything between 100 and 1,000 employees is considered to be midsize. Most of these companies need more than what Windows 7 Home Premium offers, but cannot afford the Software Assurance licences required for Windows 7 Enterprise edition.



Improvement from XP only
According to many industry professionals, Windows XP is still the most widely used operating system in the world. The Apple’s Mac iOS versions, Ubuntu and Linux all combined do not even approach the ​percentage of the market share held by Windows XP alone. Even newer versions of Windows like Visa and Windows 7 have yet to make a serious dent in the number of XP loyalists among PC owners.
This is especially surprising considering the number of improvements that both Vista and Window 7 have made over XP. For instance, the redesigned desktop seen in Vista and 7 is much improved over the traditional layout used by XP. Those icons that remain largely unused such as the ”My Computer” and ”My Network Places” icons no longer appear by default, resulting in a much cleaner appearance. 

Windows XP’s desktop looks hopelessly cluttered by comparison.




One of the biggest upgrades brought about over XP, first by Vista and then by 7, is the newfound ease in home networking. Sharing files, folders and peripherals is astonishingly easy compared to the bulky processes required by Windows XP. Of course, those problems still become obvious when confronted with a need to network between PCs running different versions of Windows. Those running Vista and 7 cooperate perfectly fine, but adding an XP-running machine into the mix can be rather challenging. Windows 7 also introduces a new feature called the Device Stage; networking between attached devices like your smartphone or MP3 player in order to transfer music, pictures and other files is now a breeze.   

Windows 7
Windows 7 is the latest release of  Microsoft Windows  a series of operating systems produced by Microsoft  for use on personal computer including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs. Windows 7 was released to manufacturing on July 22, 2009, and reached general retail availability worldwide on October 22, 2009, less than three years after the release of its predecessor,Windows Vista. Windows 7's server counterpart, Windows server 2008 R2, was released at the same time.
Unlike Windows Vista, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista was already compatible. Presentations given by Microsoft in 2008 focused on multi-touch support, a redesigned Windows shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements. Some standard applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, are not included in Windows 7;most are instead offered separately at no charge as part of the Windows Live Essentials suite.

Anatomy of Windows 7

- Gadgets


Windows 7 Requirements

in order run Windows 7, your PC must have the following:
- 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64)  processor
- 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
- 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
- DirectX 9 graphics device with WDDM 1.0 or higher driver


Aero
Windows Aero is the premium visual experience of Windows Vista. It features a translucent glass design with subtle window animations and new window colors.








Aero’s distinctive visual style combines the appearance of lightweight, translucent windows with powerful graphic advances. With Aero, you can enjoy visually appealing effects and appearance and also benefit from better access to your programs.

Windows 7 file management

File Formats and Data Stores
In Windows 7, Windows Explorer makes file management and manipulation easier for the user in several ways:
•        The preview for your application's file type is more accessible with a new button that lets users show and hide the preview pane.
•        Immersive visual stacks aggregate thumbnail images for file types in a view.
•        Windows Explorer views show useful information based on properties written with your property handler.
•        Document snippets and hit highlighting use your IFilter interface implementation to make searching and finding files easier.
•        Context-menu verbs and commands are easier than ever to implement.
By implementing all of the appropriate format handlers for the items returned from your protocol handler, search results from your custom data store can be as rich as search results from files. Libraries are automatically created for your protocol handlers so users can scope their searches easily. And the logic for creating Libraries can be easily customized through the registry.

Managing files and folders
File management is organizing and keeping track of files and folders, helping you stay organized, so information is easily located. A folder is a container for storing programs and files, similar to a folder in a file cabinet. As with a file cabinet, working with poorly managed files is like looking for a needle in a haystack—it is frustrating and time-consuming to search through irrelevant, misnamed, and out-of-date files to find the one you want. Windows allows you to organize folders and files in a file hierarchy, imitating the way you store paper documents in real folders. Just as a file cabinet contains several folders, each containing related documents with dividers grouping related folders together, so the Windows file hierarchy allows you to organize your files in folders, and then place folders in other folders. Windows 7 comes with four libraries: Documents, Pictures, Music, and Videos. Libraries (New!) are special folders that catalog folders and files in a central location. A library includes and displays folders that are stored in different locations on your computer, Home group, or network.
Using the file management tools, you can save files in folders with appropriate names for easy identification, quickly and easily create new folders so you can reorganize information and delete files and folders that you no longer need. You can also search for a file when you cannot remember where you stored it, create shortcuts to files and folders for quick and easy access, and even compress files and folders to save space.

A folder can hold different types of files, such as text, spreadsheets, and presentations. The Documents folder is the main location in Windows 7 where you store your files. However, there are some special folders, such as Pictures and Music, designed with specialized features to store specific types of files.
