If an initial event is logged, on additional failures or warnings, only the instance counter is incremented. The next time that the thread starts, event or event is logged if there are instances in the last monitoring interval.
If no problem or delay occurred during the last monitoring interval, event or event is not logged and the security channel is no longer monitored.
When the security channel detects this issue again, a new event or new event is logged, and the security channel enters the monitoring status again. When the domain controller for a trusted domain changes and there are errors or delays, event or event is logged. Therefore, the new trusted domain controller name is tracked, and a new monitoring cycle begins. The change of domain controller may be related to previous events that were logged.

Retrieved April 29, CBS Interactive. Softpedia News. Retrieved 8 June 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.
Windows Server R2 supports up to 64 physical processors [26] or up to logical processors per system. Only the Datacenter and Itanium editions can take advantage of the capability of 64 physical processors. Enterprise, the next-highest edition after those two, can only use 8. Server Core includes a subset of the. When raising the forest functional level, the Active Directory recycle bin feature is available and can be enabled using the Active Directory Module for PowerShell.
Support for the RTM version of Windows Server R2 ended on April 9, , [9] [10] and users will not be able to receive further security updates for the operating system, due to new policies requiring Service Pack 1 [31] to continue to be supported with security updates, lasting until the end of support lifecycle for that Windows operating system.
The host without the latest Windows Server R2 service pack installed is vulnerable to viruses and multiple security attacks. On January 13, , Windows Server R2 exited mainstream support and entered the extended support phase; Microsoft continued to provide security updates every month for Windows Server R2, however, free technical support, warranty claims, and design changes were no longer being offered.
Extended support ended on January 14, , about less than eleven years after the release of Windows Server R2. In August , researchers reported that "all modern versions of Microsoft Windows" may be at risk for "critical" system compromise due to design flaws of hardware device drivers from multiple providers. Dynamic Memory makes it possible for a VM to only allocate as much physical RAM as is needed temporarily for its execution.
