In , Microsoft released Windows NT 3. Unlike the Windows 9x series of operating systems, it is a fully bit operating system. In , Windows NT 4. Windows NT was originally designed to be used on high-end systems and servers, but with the release of Windows , many consumer-oriented features from Windows 95 and Windows 98 were included, such as the Windows Desktop Update , Internet Explorer 5 , USB support and Windows Media Player. These consumer-oriented features were further extended in Windows XP in , which included a new visual style called Luna , a more user-friendly interface, updated versions of Windows Media Player and Internet Explorer 6 by default, and extended features from Windows Me, such as the Help and Support Center and System Restore.
Windows Vista , which was released in , focused on securing the Windows operating system against computer viruses and other malicious software by introducing features such as User Account Control. New features include Windows Aero , updated versions of the standard games e.
Despite this, Windows Vista was critically panned for its poor performance on older hardware and its at-the-time high system requirements. Windows 7 followed in nearly three years after its launch, and despite it technically having higher system requirements,   reviewers noted that it ran better than Windows Vista. Windows 8 , which was released in , introduced many controversial changes, such as the replacement of the Start menu with the Start Screen, the removal of the Aero interface in favor of a flat, colored interface as well as the introduction of “Metro” apps later renamed to Universal Windows Platform apps , and the Charms Bar user interface element, all of which received considerable criticism from reviewers.
The following version of Windows, Windows 10 , which was released in , reintroduced the Start menu and added the ability to run Universal Windows Platform apps in a window instead of always in full screen.
Windows 10 was generally well-received, with many reviewers stating that Windows 10 is what Windows 8 should have been. The latest version of Windows, Windows 11 , was released on October 5, Windows 11 incorporates a redesigned user interface, including a new Start menu, a visual style featuring rounded corners, and a new layout for the Microsoft Store,  and also included Microsoft Edge by default.
The first independent version of Microsoft Windows, version 1. The project was briefly codenamed “Interface Manager” before the windowing system was implemented—contrary to popular belief that it was the original name for Windows and Rowland Hanson , the head of marketing at Microsoft, convinced the company that the name Windows would be more appealing to customers. Windows 1. The first version of Microsoft Windows included a simple graphics painting program called Windows Paint ; Windows Write , a simple word processor ; an appointment calendar; a card-filer; a notepad ; a clock; a control panel ; a computer terminal ; Clipboard ; and RAM driver.
Microsoft had worked with Apple Computer to develop applications for Apple’s new Macintosh computer, which featured a graphical user interface. As part of the related business negotiations, Microsoft had licensed certain aspects of the Macintosh user interface from Apple; in later litigation, a district court summarized these aspects as “screen displays”. In the development of Windows 1. For example, windows were only displayed “tiled” on the screen; that is, they could not overlap or overlie one another.
On December 31, , Microsoft declared Windows 1. Microsoft Windows version 2. Much of the popularity for Windows 2. Microsoft Windows received a major boost around this time when Aldus PageMaker appeared in a Windows version, having previously run only on Macintosh. Some computer historians [ who? Like prior versions of Windows, version 2. In such a configuration, it could run under another multitasker like DESQview , which used the protected mode.
It was also the first version to support the High Memory Area when running on an Intel compatible processor. Version 2. In Apple Computer, Inc. Microsoft Corp.
Judge William Schwarzer dropped all but 10 of Apple’s claims of copyright infringement, and ruled that most of the remaining 10 were over uncopyrightable ideas. On December 31, , Microsoft declared Windows 2. Windows 3.
A few months after introduction, Windows 3. A “multimedia” version, Windows 3. This version was the precursor to the multimedia features available in Windows 3. The features listed above and growing market support from application software developers made Windows 3. Support was discontinued on December 31, Its API was incompatible with Windows. Version 1. They cooperated with each other in developing their PC operating systems, and had access to each other’s code. After an interim 1.
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.
The hardware acceleration for display is also turned off by default, users have to turn the acceleration level up themselves if they trust the display card driver. Among the new features are a number of management features for branch offices, file serving, printing and company-wide identity integration. Windows Server R2, an update of Windows Server , was released to manufacturing on December 6, The other CD adds many optionally installable features for Windows Server The R2 update was released for all x86 and x64 versions, except Windows Server R2 Enterprise Edition, which was not released for Itanium.
It is designed to use the expanded bit memory address space provided by the x86—64 architecture. Windows XP Professional x64 Edition is based on the Windows Server codebase, with the server features removed and client features added. It is only available to Software Assurance customers. The aim of WinFLP is to give companies a viable upgrade option for older PCs that are running Windows 95, 98, and Me that will be supported with patches and updates for the next several years.
Most user applications will typically be run on a remote machine using Terminal Services or Citrix. While being visually the same as Windows XP, it has some differences.
For example, if the screen has been set to 16 bit colors, the Windows recycle bin icon and some XP bit icons will show. Paint and some games like Solitaire aren’t present too. Windows Home Server code-named Q, Quattro is a server product based on Windows Server , designed for consumer use. The system was announced on January 7, , by Bill Gates. Windows Home Server can be configured and monitored using a console program that can be installed on a client PC.
Such features as Media Sharing, local and remote drive backup and file duplication are all listed as features. Windows Vista was released on November 30, , to business customers—consumer versions followed on January 30, Windows Vista intended to have enhanced security by introducing a new restricted user mode called User Account Control , replacing the “administrator-by-default” philosophy of Windows XP. Vista was the target of much criticism and negative press, and in general was not well regarded, this was seen as leading to the relatively swift release of Windows 7.
One major difference between Vista and earlier versions of Windows, Windows 95 and later, was that the original start button was replaced with the Windows icon in a circle called the Start Orb. Windows Vista had the version number NT 6. During its lifetime, Windows Vista had two service packs. Windows Vista shipped in six editions : .
All editions except Starter edition were available in both bit and bit versions. The biggest advantage of the bit version was breaking the 4 gigabyte memory barrier, which bit computers cannot fully access.
Windows Server built on the technological and security advances first introduced with Windows Vista, and was significantly more modular than its predecessor, Windows Server Windows 7 was released to manufacturing on July 22, , and reached general retail availability on October 22, The interface was renewed with a bigger taskbar and some improvements in the searching system and the Start menu. Windows 7 met with positive reviews, which said the OS was faster and easier to use than Windows Vista.
Windows 7 shipped in six editions : . In some countries in the European Union , there were other editions that lacked some features such as Windows Media Player, Windows Media Center and Internet Explorer—these editions were called names such as “Windows 7 N. All editions, except the Starter edition, were available in both bit and bit versions. Unlike the corresponding Vista editions, the Professional and Enterprise editions were supersets of the Home Premium edition.
Windows Server R2 shipped in bit versions x64 and Itanium only. WinTPC was available for software assurance customers and relied on cloud computing in a business network. It allows routers experiencing congestion to mark packets and allow clients to automatically lower their transfer rate to prevent further packet loss.
The receiver echoes the congestion indication to the sender, which must react as though a packet drop were detected. Possible settings are: enabled, disabled, default restores the state to the system default. Default state: disabled. May be worth trying “enabled” for gaming with unstable connections. Its effect on bulk throughput with large TCP Window are less clear. Currently, we do not recommend enabling this setting, as reportedly it has negative impact on throughput with some residential US ISPs.
EA multiplayer games that require a profile logon do not support ECN as well you will not be able to logon. However, it can also reduce latency in some games with ECN-capable routers in the presence of packet loss dropped packets. The problem with timestamps is that they add 12 bytes to the byte TCP header of each packet, so turning them on causes considerable overhead.
Possible states: enabled,disabled,default Default state: disabled Recommended: disabled. Retransmit timeout RTO determines how many milliseconds of unacknowledged data it takes before the connection is aborted. The default timeout for Initial RTO of 3 seconds can usually be lowered for low-latency modern broadband connections, unless you’re in a remote location, on a satellite internet connection, or experiencing high latency.
In high-latency situations, this can increase retransmissions if the RTO value is reached on a regular basis. The command is:. Possible states: enabled,disabled,default Default state: disabled Recommended: “disabled” for stable connections without much latency variations, “enabled” for connections with fluctuating ping and in the presence of packet loss. Note: This property only supported in Windows 8.
Windows 7 hotfix displays it in netsh as a read-only setting. TCP slow start only sends two frames, waits for ACK response, and increases speed exponentially provided there are no dropped packets. This slow start algorithm can also be activated if there is no traffic for ms. This is not optimal for fast internet connections with intermittent bursts of data. The following should work for server, however it does not work in Windows 8.
It is sometimes useful to view and set the Maximum Transmission Unit MTU value for a specific network adapter manually. To view a list of active network interfaces, their names and their respective MTU values in Windows 8, open PowerShell or command prompt as administrator and run the following command:. For example, if the name of your network card is “Wi-Fi” and you’d like to set its MTU to , you’d have to type:. Below is a list of what we’ve confirmed to work.
To edit the Windows Registry, click the Windows button, and type: regedit in the search dialog you may have to right-click regedit and choose to run as administrator to have the proper write permissions. It is always a good idea to create a restore point and backup the registry before making changes.
TTL does not directly affect speed, and can be safely left alone in many cases. A number that’s too small risks packets being discarded before reaching their destination.
A number that’s too large over will cause delay in when lost IP packets are discarded. It is important to note that this increases their priority compared to the hundreds of other running processes, while keeping their order. See our Host Resolution Priority Tweak article for more details. The registry location under Windows 8, 8. However, under heavy network load it may be necessary to adjust these two registry settings to increase port availability and decrease the time to wait before reclaiming unused ports.
If the default limits are exceeded under heavier loads, the following error is observed ” address in use: connect exception “. Recommended: 30 decimal, denoting 30 seconds – time to wait before reclaiming ports, in seconds. Default time before reclaiming ports, if value is at 0xffffffff or not present in the registry is or seconds, depending on your OS.
Just reducing the delay is often sufficient without changing MaxUserPort, as it allows for reusing ports more efficiently. Note this only has effect in the presence of running QoS applications that request priority traffic, like Windows Update, for example.
Recommended: 0 , possible values between 0 and – indicates the percentage value of reserved bandwidth for QoS applications. Set to 0 to disable. In order to define DiffServ DSCP values, according to Microsoft the machine needs to have joined a domain, and interfaces have to see the domain controller. To overcome this limitation, so that you can tag DSCP values even for adapters that do not have access to a domain, use the following hidden registry key:.
Notes: gpedit. This registry key may also be needed in systems with multiple network adapters present. When this happens, you can usually see the following error in the Event Viewer System log: Event ID: “The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations. To avoid those errors, you need to change the way Windows allocates memory for network services and file sharing.
The below settings optimize the machine as a file server so it would allocate resources accordingly. There are two related registry settings:. In addition to explorer. For more information, see our Web Browser Tweaks article. Note: Increasing this setting much over 10 can cause incomplete page loading and other issues with some pages.
The idea behind such throttling is that processing of network packets can be a resource-intensive task, and it may need to be throttled to give prioritized CPU access to multimedia programs.
In some cases, such as Gigabit networks and some online games, for example, it is beneficial to turn off such throttling all together for achieving maximum throughput.
It is only recommended to change this setting in saturated Gigabit LAN environments, where you do not want to give priority to multimedia playback. Reportedly, disabling throttling by using ffffffff can also help reduce ping spikes in some online games.
This setting, in combination with the above “NetworkThrottlingIndex” can help some games and video streaming. In some server operating systems Windows Server , the SystemResponsiveness may be set to , instead of 20 by default.
This is by design, giving higher priority to background services over multimedia. See also: MSDN ms Nagle’s algorithm is designed to allow several small packets to be combined together into a single, larger packet for more efficient transmissions. Keep in mind that disabling Nagle’s algorithm may also have some negative effect on file transfers. Nagle’s algorithm is enabled in Windows by default. To implement this tweak and disable Nagle’s algorithm, modify the following registry keys. Find the correct one with your IP address listed.
For gaming performance, recommended is 1 disable. For pure throughput and data streaming, you can experiment with small values over 2. Wifi performance may see a slight improvement with disabled TcpAckFrequency as well. Note you can also set this to 1 to reduce the nagle effect from the default of ms without disabling it.
Note that only version 4 of the prorgam supports Windows 8 and newer and works with PowerShell cmdlets. There program is available in our downloads section. More detailed information about all available options is provided in the TCP Optimizer documentation , answers to frequently asked questions are available in the Optimizer FAQ , and personalized help is available through our forums.

Home » Articles » Registry Tweaks. What about registry tweaks? Nagle’s algorithm applies to TCP packets only. It was designed to buffer data small 1-byte keystrokes, for example until a full packet’s worth is collected before sending it out.
Is there any tweaks to improve UDP? Many games use TCP as well, disabling Nagling is well documented and tested for reducing latency in some games. Check the Gaming Tweaks article. If you use up all your bandwidth regardless of the protocol , you will experience delays and other congestion issues. We can discuss this in more detail on the forums if you’d like.
Thank you for the info, this info fixed one of the issues I had. Heuristics restricts autotuning if the connection type is “Public”, for security reasons. So if your connection is “Public” try the following: 1.
If experiencing problems: 3. TcpTimedWaitDelay i wouldnt set this to 30 second why ,here is ms : The TcpTimedWaitDelay registry setting defaults to a value seconds, which represents 2 times the maximum segment lifetime of seconds or 4 minutes.
However, you can use this entry to customize the interval. Reducing the value of this entry allows TCP to release closed connections faster, providing more resources for new connections. However, if the value is too low, TCP might release connection resources before the connection is complete, requiring the server to use additional resources to re-establish the connection. This registry setting can be set from 0 to seconds. The only downside of closing the connection is a very small overhead if it the need arises for it to be established again.
And i know that if TCP is set to It will pretty much grab all the bandwidth and cause udp issue But if I set udp lower say 80 byte then the CPU will have a fitting caught. Evil if you do evil if you don’t? All rights reserved. Broadband Forums General Discussions.
