Microsoft would later imitate much of it in Windows Still, much of the system had bit code internally which required, among other things, device drivers to be bit code as well. It also removed Real Mode, and only ran on an or better processor. Later Microsoft also released Windows 3.
In and , Microsoft released Windows for Workgroups WfW , which was available both as an add-on for existing Windows 3. Windows for Workgroups included improved network drivers and protocol stacks, and support for peer-to-peer networking. There were two versions of Windows for Workgroups, WfW 3. Unlike prior versions, Windows for Workgroups 3. All these versions continued version 3. Even though the 3.
The Windows API became the de facto standard for consumer software. On December 31, , Microsoft declared Windows 3. Meanwhile, Microsoft continued to develop Windows NT. This successor was codenamed Cairo. In hindsight, Cairo was a much more difficult project than Microsoft had anticipated and, as a result, NT and Chicago would not be unified until Windows XP —albeit Windows , oriented to business, had already unified most of the system’s bolts and gears, it was XP that was sold to home consumers like Windows 95 and came to be viewed as the final unified OS.
Driver support was lacking due to the increased programming difficulty in dealing with NT’s superior hardware abstraction model. This problem plagued the NT line all the way through Windows Programmers complained that it was too hard to write drivers for NT, and hardware developers were not going to go through the trouble of developing drivers for a small segment of the market. Additionally, although allowing for good performance and fuller exploitation of system resources, it was also resource-intensive on limited hardware, and thus was only suitable for larger, more expensive machines.
However, these same features made Windows NT perfect for the LAN server market which in was experiencing a rapid boom, as office networking was becoming common.
Windows NT version 3. The Win32 API had three levels of implementation: the complete one for Windows NT, a subset for Chicago originally called Win32c missing features primarily of interest to enterprise customers at the time such as security and Unicode support, and a more limited subset called Win32s which could be used on Windows 3. Thus Microsoft sought to ensure some degree of compatibility between the Chicago design and Windows NT, even though the two systems had radically different internal architectures.
Windows NT was the first Windows operating system based on a hybrid kernel. The hybrid kernel was designed as a modified microkernel , influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, but without meeting all of the criteria of a pure microkernel. As released, Windows NT 3.
The 3. Support for Windows NT 3. After Windows 3. The Win32 API first introduced with Windows NT was adopted as the standard bit programming interface, with Win16 compatibility being preserved through a technique known as ” thunking “. A new object-oriented GUI was not originally planned as part of the release, although elements of the Cairo user interface were borrowed and added as other aspects of the release notably Plug and Play slipped.
Microsoft did not change all of the Windows code to bit; parts of it remained bit albeit not directly using real mode for reasons of compatibility, performance, and development time. Additionally it was necessary to carry over design decisions from earlier versions of Windows for reasons of backwards compatibility, even if these design decisions no longer matched a more modern computing environment.
These factors eventually began to impact the operating system’s efficiency and stability. Microsoft marketing adopted Windows 95 as the product name for Chicago when it was released on August 24, Microsoft had a double gain from its release: first, it made it impossible for consumers to run Windows 95 on a cheaper, non-Microsoft DOS, secondly, although traces of DOS were never completely removed from the system and MS DOS 7 would be loaded briefly as a part of the booting process, Windows 95 applications ran solely in enhanced mode, with a flat bit address space and virtual memory.
These features make it possible for Win32 applications to address up to 2 gigabytes of virtual RAM with another 2 GB reserved for the operating system , and in theory prevented them from inadvertently corrupting the memory space of other Win32 applications.
Three years after its introduction, Windows 95 was succeeded by Windows Unlike with Windows 3. Microsoft case, blaming unfair marketing tactics on Microsoft’s part. Some companies sold new hard drives with OSR2 preinstalled officially justifying this as needed due to the hard drive’s capacity.
The first Microsoft Plus! Microsoft ended extended support for Windows 95 on December 31, Microsoft released the successor to NT 3.
It was Microsoft’s primary business-oriented operating system until the introduction of Windows Microsoft ended mainstream support for Windows NT 4. Both editions were succeeded by Windows Professional and the Windows Server Family, respectively. This edition was succeeded by Windows XP Embedded.
On June 25, , Microsoft released Windows 98 code-named Memphis , three years after the release of Windows 95 , two years after the release of Windows NT 4. USB support in Windows 98 is marketed as a vast improvement over Windows The release continued the controversial inclusion of the Internet Explorer browser with the operating system that started with Windows 95 OEM Service Release 1. The action eventually led to the filing of the United States v.
Microsoft case, dealing with the question of whether Microsoft was introducing unfair practices into the market in an effort to eliminate competition from other companies such as Netscape. In , Microsoft released Windows 98 Second Edition, an interim release. One of the more notable new features was the addition of Internet Connection Sharing , a form of network address translation , allowing several machines on a LAN Local Area Network to share a single Internet connection.
Hardware support through device drivers was increased and this version shipped with Internet Explorer 5. Many minor problems that existed in the first edition were fixed making it, according to many, the most stable release of the Windows 9x family. Mainstream support for Windows 98 and 98 SE ended on June 30, , and ended extended support on July 11, It has the version number Windows NT 5.
Windows has had four official service packs. It was successfully deployed both on the server and the workstation markets. Amongst Windows ‘s most significant new features was Active Directory , a near-complete replacement of the NT 4.
Terminal Services , previously only available as a separate edition of NT 4, was expanded to all server versions. A number of features from Windows 98 were incorporated also, such as an improved Device Manager, Windows Media Player , and a revised DirectX that made it possible for the first time for many modern games to work on the NT kernel.
Windows is also the last NT-kernel Windows operating system to lack product activation. While Windows upgrades were available for Windows 95 and Windows 98, it was not intended for home users.
It was the last DOS-based operating system from Microsoft. Windows Me introduced a new multimedia-editing application called Windows Movie Maker , came standard with Internet Explorer 5. System Restore was a notable feature that would continue to thrive in all later versions of Windows.
Windows Me was conceived as a quick one-year project that served as a stopgap release between Windows 98 and Windows XP. Many of the new features were available from the Windows Update site as updates for older Windows versions System Restore and Windows Movie Maker were exceptions. Windows Me was criticized for stability issues, as well as for lacking real mode DOS support, to the point of being referred to as the “Mistake Edition.
The initial release was met with considerable criticism , particularly in the area of security , leading to the release of three major Service Packs.
Service Pack 2 provided significant improvements and encouraged widespread adoption of XP among both home and business users. Windows XP was one of Microsoft’s longest-running flagship operating systems, beginning with the public release on October 25, , for at least 5 years, and ending on January 30, , when it was succeeded by Windows Vista.
On April 25, , Microsoft launched Windows Server , a notable update to Windows Server encompassing many new security features, a new “Manage Your Server ” wizard that simplifies configuring a machine for specific roles, and improved performance. It is based on the Windows NT 5. A few services not essential for server environments are disabled by default for stability reasons, most noticeable are the “Windows Audio” and “Themes” services; users have to enable them manually to get sound or the ” Luna ” look as per Windows XP.

Windows Server Comparison of editions and features – 4sysops.
This means that if you are installing Windows Server R2 on a physical box you are probably using it as a host machine for Hyper-V to run your virtual machines in your network. Those free virtual machines licenses are called the virtualization rights. This is where the reasoning for Datacenter comes into play. With Standard edition, you got 2 virtualization rights but with Windows Server R2 Data Center edition you get unlimited virtualization rights. In this case, unlimited means as many virtual machines as your hardware platform can support.
Why would anyone buy Standard edition with its 2 virtualization rights when you could buy Data Center edition and get unlimited rights? The general rule of thumb is that if you are running more than 10 VMs and have an advanced hardware platform read datacenter then the datacenter edition will be a more cost-effective choice. If not then you probably want Standard one.
Microsoft has built this stand-alone version of Hyper-V that truly does stand alone in that it does not come with the full version of Windows Server R2 operating system. Really Cool! I really want the benefits of running Hyper-V in its R2 version. I could download and install it as the platform for my already licensed servers.
Now if you choose to add new VMs running WS R2 you will need to purchase licenses at which time you would get virtualization rights and would at that time have to decide whether you wanted to continue with Hyper-V server or simply move to Hyper-V on Windows Server R2.
November 20, 3 min to read. Chris Henley. The beauty is that you win either way and Hyper-V stays the way it should always be. He is a published author and a regular speaker and presenter at user groups and major technology conferences around the world. On May 21 st , Windows Server R2 was introduced and is now the latest version of Windows Server in the market.
Microsoft has released four different editions of Windows Server varying in cost, licensing and features. This edition of Windows Server is targeted towards small businesses of up to 15 users. Foundation edition can be implemented in environments where features such as file sharing, printer sharing, security and remote access are required. The Windows Server R2 Essentials edition is the next step up, also geared towards small businesses of up to 25 users.
Windows Server R2 Essentials edition is available in retail stores around the world making it easy for businesses to install the new operating system without necessarily purchasing new hardware.
Windows Server R2 Essentials edition can run a single instance of virtual machine on Hyper V, a feature that was not available in Windows Server Essentials non-R2 edition. This single virtual machine instance can be Windows Server R2 Essential edition only, seriously limiting the virtualization options but allowing companies to begin exploring the benefits of the virtualization platform.
The Standard edition is able to support an unlimited amount of users, as long as the required user licenses have been purchased. We should note that the Standard edition supports up to 2 Virtual Machines.
The Windows Server R2 Datacenter edition is the flagship product created to meet the needs of medium to large enterprises. The major difference between the Standard and Datacenter edition is that the Datacenter edition allows the creation of unlimited Virtual Machines and is therefore suitable for environments with extensive use of virtualization technology.
Before purchasing the Windows Server operating system, it is very important to understand the difference between various editions, the table below shows the difference between the four editions of Windows Server For example, a CAL assigned to a user, allows only that user to access the server via any device.
Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server. We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach:. Assume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations. In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server.
In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devices , e. Windows Server Foundation is available to OEMs Original Equipment Manufacturers only and therefore can only be purchased at the time of purchasing a n new hardware server. Windows Foundation edition supports up to 15 users. In addition, Foundation edition owners cannot upgrade to other editions. The Essential edition of server is available to OEMs with the purchase of new hardware and also at retail stores.
The user limit of this server edition is 25 and device limit is This means that a maximum of 25 users amongst 50 computers can access the Windows Server Essentials edition.
For example, you have 20 users rotating randomly amongst 25 computers accessing the Server Essentials edition, without any problem.
A common question at this point is what if the organization expands and increases its users and computers? In these cases Microsoft provides an upgrade path allowing organizations to upgrade to the Windows Server Standard or Datacenter edition license and perform an in-place license transition.
Once the transition is complete, the user limitation, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server should keep in mind that it will be necessary to purchase the required amount of CALs or DALs according to their users or devices. Administrators will be happy to know that it is also possible to downgrade the Standard edition of Server to the Essentials edition.
For example, it is possible to run Essential edition of Server as virtual machine utilizing one of two available virtual instances in Standard edition as shown in the figure below. This eliminates the needs to purchase Essential edition of Server Download Now!
