April 2010 Learn how and when to remove this template message The initial design and planning of Windows 95 can be traced back to around March 1992, [6] [7] [8] just after the release of Windows 3.

At this time, Windows for Workgroups 3. Cairo would be Microsoft's next-generation operating system based on Windows NT and featuring a new user interface and an object-based file system, but it was not planned to be shipped before 1994.

Simultaneously with Windows 3. Microsoft realized they were in need of an updated version of Windows that could support 32-bit applications and preemptive multitasking, but could still run on low-end hardware Windows NT did not. So the development of Windows "Chicago" was started and, as it was planned for a late 1993 release, became known as Windows 93.

Initially, the decision was made not to include a new user interface, as this was planned for Cairo, and only focus on making installation, configuration, and networking easier. The first version of Chicago's feature specification was finished on September 30, 1992. Cougar was to become Chicago's kernel.

During the preview period, Microsoft established various electronic distribution points for promotional and technical documentation on Chicago, [9] including a detailed document for media reviewers describing the new system highlights.

Architecture[ edit ] Architectural diagram Windows 95 was designed to be maximally compatible with existing MS-DOS and 16-bit Windows programs and device driverswhile offering a more stable and better performing system. The lowest level of the operating system consists of a large number of virtual device drivers VxDs running in 32-bit protected mode and one or more virtual DOS machines running in virtual 8086 mode.

The virtual device drivers are responsible for handling physical devices such as video and network cardsemulating virtual devices used by the virtual machines or providing various system services.

The three most important virtual device drivers are: VXD Responsible for memory management, event handlinginterrupt handlingloading and initializing virtual device drivers, creating new virtual machines and thread scheduling. Each physical media has its own device driver: In case there is no native Windows driver for a certain storage device, or if a device is forced to run in compatibility mode, the Real Mode Mapper can access it through MS-DOS.

Memory area outside the segment cannot be accessed by a program. If a program crashes, nothing else is harmed.

A crashing Windows 3. The Win32 API is implemented by three modules, each consisting of a 16-bit and a 32-bit component: Kernel Provides high level access to memory and process managementand access to the file system. User Responsible for managing and drawing the various user interface components, such as windowsmenus and buttons. Responsible for drawing graphics in a device-independent way.

For example, it is possible to prevent the loading of the graphical user interface and boot the system into a real-mode MS-DOS environment. This sparked debate amongst users and professionals regarding the extent to which Windows 95 is an operating system or merely a graphical shell running on top of MS-DOS.

MS-DOS itself is demoted to a compatibility layer for 16-bit device drivers. Windows 95 is capable of using all 16-bit Windows 3. SYS is still required to boot Windows 95. SYS have no effect on Windows programs. DOS games, which could not be executed on Windows 3.

Navigation menu

As with Windows 3. On startup, the MS-DOS component in Windows 95 responds to a pressed F8 key by temporarily pausing the default boot process and presenting the DOS boot options menu, allowing the user to continue starting Windows normally, start Windows in safe mode or exit to the DOS prompt.

It is even possible for MS-DOS to run out of conventional memory while doing so, preventing the program from launching. Since the segments were allocated as fixed, Windows could not move them, which would prevent any more programs from launching. User interface[ edit ] Windows 95 introduced a redesigned shell based around a desktop metaphor ; the desktop was re-purposed to hold shortcuts to applications, files and folders.

In Windows 95, the currently running applications were displayed as buttons on a taskbar across the bottom of the screen. The taskbar also contained a notification area used to display icons for background applications, a volume control and the current time. The Start menuinvoked by clicking the "Start" button on the taskbar, was introduced as an additional means of launching applications or opening documents. While maintaining the program groups used by its predecessor Program Managerit also displayed applications within cascading sub-menus.

The previous File Manager program was replaced by Windows Explorer. The user interface looked dramatically different from prior versions of Windows, but its design language did not have a special name like Metro or Aqua or Material Design. Internally it was called "the new shell" and later simply "the shell". Some of the user interface elements introduced in Windows 95, such as the desktop, taskbar, Start menu and Windows Explorer file manager, remained fundamentally unchanged on future versions of Windows.

Windows 95 included support for 255-character mixed-case long filenames [21] and preemptively multitasked protected-mode 32-bit applications.

The Differences Between Mac, Windows, and Linux

Long file names[ edit ] 32-bit File Access is necessary for the long file names feature introduced with Windows 95 through the use of the VFAT file system extension. It is available to both Windows programs and MS-DOS programs started from Windows they have to be adapted slightly, since accessing long file names requires using larger pathname buffers and hence different system calls.

Competing DOS-compatible operating systems released before Windows 95 cannot see these names. Using older versions of DOS utilities to manipulate files means that the long names are not visible and are lost if files are moved or renamed, as well as by the copy but not the originalif the file is copied. During a Windows 95 automatic upgrade of an older Windows 3. When Windows 95 is started in DOS mode, e.

In case the need arises to depend on disk utilities that do not recognize long file names, such as the MS-DOS 6. While the OS kernel is 32-bit, much code especially for the user interface remained 16-bit for performance reasons as well as development time constraints.

This had a rather detrimental effect on system stability and led to frequent application crashes. The introduction of 32-bit file access in Windows for Workgroups 3. DOS can be used for running old-style drivers for compatibility, but Microsoft discourages using them, as this prevents proper multitasking and impairs system stability.

Control Panel allows a user to see which MS-DOS components are used by the system; optimal performance is achieved when they are bypassed. The Windows kernel uses MS-DOS style real-mode drivers in Safe Modewhich exists to allow a user to fix problems relating to loading native, protected-mode drivers.

These minimal claims were made in order to maximize the available market of Windows 3. This configuration would rely heavily on virtual memory and was only optimal for productive use on single-tasking dedicated workstations. Office 2000 is the last version of Microsoft Office compatible with Windows 95. Similarly, Windows Media Player 7.

On December 31, 2001, Microsoft ended its support for Windows 95, making it an "obsolete" product per the Microsoft Lifecycle Policy. In addition, some video game enthusiasts choose to use Windows 95 for their legacy system to play old DOS games, although some other versions of Windows such as Windows 98 can also be used for this purpose. DMF was a special 21-sector format that Microsoft used to store 1. At the release date of Windows 95, Internet Explorer 1. Pack did not reach as many retail consumers as the operating system itself it was mainly advertised for its non-Internet-related add-ons such as themes and better disk compression but was usually included in pre-installed OEM sales, and at the time of Windows 95's release, the web was being browsed mainly with a variety of early web browsers such as NCSA Mosaic and Netscape Navigator promoted by products such as Internet a comparison of macintosh and windows 95 on its overall functionality a Box.

While there was no uninstaller, it could be deleted easily if desired. While only the 4.

Editing the installer's configuration file located in a temporary folder would make the feature available in the installer. Alternatively, the user could install IE4 with the desktop update before installing a newer version of Internet Explorer. Release and promotion[ edit ] Microsoft Windows 95 operating system cover shot The Windows 95 release included a commercial featuring The Rolling Stones ' 1981 single " Start Me Up " a reference to the Start button.

However, Microsoft said that this was just a rumor spread by the band to increase their market value, and the company actually paid a fraction of that amount. In the UK, the largest computer chain PC World received a large quantity of point-of-sale material; many branches opened at midnight to sell the first copies of the product. Copies of The Times were available for free, and Microsoft paid for 1. Only the original release was sold as a shrink-wrapped product; later editions were provided only to computer OEMs for installation on new PCs.

Together with the introduction of Windows 95, Microsoft released the Microsoft Plus!

The first service pack was made available half a year after the original release and fixed a number of small bugs. This release was never made available to end-users directly and was only sold through OEMs with the purchase of a new PC.

A full third service pack was never released, but two smaller updates to the second were released in the form of a USB Supplement OSR 2. Both were available as stand-alone updates and as updated disc images shipped by OEMs.
