Microsoft Windows referred to as Windows, is a group of several proprietary graphical operating system families, all of which are developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. Active Microsoft Windows families include Windows NT and Windows IoT. Defunct Microsoft Windows families include Windows Mobile and Windows Phone. Microsoft introduced an operating environment named Windows on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces. Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, introduced in 1984. Apple came to see Windows as an unfair encroachment on their innovation in GUI development as implemented on products such as the Lisa and Macintosh. On PCs, Windows is still the most popular operating system. However, in 2014, Microsoft admitted losing the majority of the overall operating system market to Android, because of the massive growth in sales of Android smartphones.

In 2014, the number of Windows devices sold was less than 25 %. This comparison, may not be relevant, as the two operating systems traditionally target different platforms. Still, numbers for server use of Windows show one third market share, similar to that for end user use; as of October 2018, the most recent version of Windows for PCs, tablets and embedded devices is Windows 10. The most recent version for server computers is Windows Server, version 1903. A specialized version of Windows runs on the Xbox One video game console. Microsoft, the developer of Windows, has registered several trademarks, each of which denote a family of Windows operating systems that target a specific sector of the computing industry; as of 2014, the following Windows families were being developed: Windows NT: Started as a family of operating systems with Windows NT 3.1, an operating system for server computers and workstations. It now consists of three operating system subfamilies that are released at the same time and share the same kernel: Windows: The operating system for mainstream personal computers and smartphones.

The latest version is Windows 10. The main competitor of this family is macOS by Apple for personal computers and Android for mobile devices. Windows Server: The operating system for server computers; the latest version is Windows Server 2019. Unlike its client sibling, it has adopted a strong naming scheme; the main competitor of this family is Linux. Windows PE: A lightweight version of its Windows sibling, meant to operate as a live operating system, used for installing Windows on bare-metal computers, recovery or troubleshooting purposes; the latest version is Windows PE 10. Windows IoT: Initially, Microsoft developed Windows CE as a general-purpose operating system for every device, too resource-limited to be called a full-fledged computer. However, Windows CE was renamed Windows Embedded Compact and was folded under Windows Compact trademark which consists of Windows Embedded Industry, Windows Embedded Professional, Windows Embedded Standard, Windows Embedded Handheld and Windows Embedded Automotive.

The following Windows families are no longer being developed: Windows 9x: An operating system that targeted consumers market. Discontinued because of suboptimal performance. Microsoft now caters to the consumer market with Windows NT. Windows Mobile: The predecessor to Windows Phone, it was a mobile phone operating system; the first version was called Pocket PC 2000. The last version is Windows Mobile 6.5. Windows Phone: An operating system sold only to manufacturers of smartphones; the first version was Windows Phone 7, followed by Windows Phone 8, the last version Windows Phone 8.1. It was succeeded by Windows 10 Mobile; the term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are categorized as follows: The history of Windows dates back to 1981, when Microsoft started work on a program called "Interface Manager", it was announced in November 1983 under the name "Windows", but Windows 1.0 was not released until November 1985.

Windows 1.0 was to achieved little popularity. Windows 1.0 is not a complete operating system. The shell of Windows 1.0 is a program known as the MS-DOS Executive. Components included Calculator, Cardfile, Clipboard viewer, Control Panel, Paint, Reversi and Write. Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only modal dialog boxes may appear over other windows. Microsoft sold as included Windows Development libraries with the C development environment, which included numerous windows samples. Windows 2.0 was released in December 1987, was more popular than its predecessor. It features several improvements to the user memory management. Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit agains

Francisco Martin Duran is an American criminal, known for his actions of October 29, 1994, when he fired 29 rounds from an SKS rifle at the White House. Duran was convicted of attempting to assassinate United States president Bill Clinton and sentenced to 40 years in prison. On Saturday October 29, 1994, dressed in a trench coat, Duran approached the fence overlooking the north lawn of the White House and fired a 7.62×39mm SKS semi-automatic rifle at a group of men wearing dark business suits on the White House lawn. Two nearby boys claimed they had remarked aloud just before the shooting that one of the men looked like Clinton. Secret Service agents began running across the lawn, with their guns drawn, when citizens Harry Rakosky, Ken Davis, Robert Haines tackled Duran and pinned his arms until he could be subdued. Clinton was inside watching a football game at the time of the shooting and was not harmed; the incident followed just six weeks after Frank Eugene Corder crashed a Cessna into the White House south lawn and prompted debate about closing off traffic on that area of Pennsylvania Avenue.

No one was injured in the assassination attempt. The most important charges in the two-week trial were attempted murder of the president and four counts of assaulting a federal officer. Duran had served prison time convicted of aggravated assault with a vehicle in the U. S. Army, therefore, beyond the attempted murder of the President he was charged with illegal possession of a firearm by a convicted felon; the other charges were use of an assault weapon during a crime of violence, destruction of U. S. property, interstate transportation of a firearm with intent to commit a felony. Duran pleaded not guilty and mounted an insanity defense, claiming that he was trying to save the world by destroying an alien "mist", connected by an umbilical cord to an alien in the Colorado mountains. Prosecutors stated he was faking insanity and called more than 60 witnesses to testify that Duran hated government in general and President Clinton in particular; the jury deliberated for under five hours to reject the insanity defense and arrive at the guilty verdict.

As of 2013, Duran is serving his sentence at the medium-security Federal Correctional Institution at Florence Federal Correctional Complex in Florence, Colorado. The Bureau of Prisons projects his release date to be the year 2029. November 19, 1994 Washington Post article March 23, 1995 Washington Post article Public Eye speculation on Duran's motivations

North 30th Street is a two-way street that runs south–north in the North Omaha area of Omaha, Nebraska. With the street beginning at Dodge Street significant sections include those from Dodge to Lake Street, from Fort Street to Laurel Avenue, from Weber to Bondesson Streets. Twelve years before the city of Omaha was founded, Mormon pioneers built the Weber Mill at the long-time northern end of North 30th Street; the Florence Park, on North 30th Street, was the town square of Winter Quarters of the Mormon pioneers. The settlement morphed into the town of Florence, its main street was located along present-day North 30th. In 1856 town settlers built the Bank of Florence at present-day 8502 North 30th Street. In 1868 the Department of the Platte built Fort Omaha in the then-void between the town of Saratoga and Florence. Today the Fort is a historic district on the National Register of Historic Places, with the Gen. George Crook House built in 1879 and the Omaha Landmark Guardhouse as contributing properties.

The Fort's boundaries include North 30th Street. Built in 1887 at a different location in Florence, the Florence Depot was moved to North 30th Street in 1971 to serve as a museum. Miller Park was built in 1891 according to renowned landscape architect Horace Cleveland's plans for the city; the current Howard Kennedy School building, serving as a public school along North 30th, was opened in 1916. The Harry Buford House was built by a leader in the city's African American community in 1929. Under the pretense of national security, in the 1940s the United States War Department approved the City of Omaha's application to widen North 30th Street to serve as the main arterial through the city's north side; the removal of the Omaha and Council Bluffs Railway and Bridge Company's streetcar line along the street was required for the project to be completed. In 1953 Sabastiono Caniglia bought a restaurant at the intersection of Fort and North 30th Streets which became his notable Mister C's, it closed in 2007.

Along with Florence, there are several notable historic neighborhoods. Beginning at Dodge Street in Downtown Omaha, the neighborhoods include Near North Omaha, Gifford Park, Miller Park and Minne Lusa. In addition to serving as the city's thoroughfare for U. S. Route 75, there are several important traffic connections along North 30th, they include Dodge Street, the major east–west low-density arterial from the Missouri River to 90th Street, where it becomes West Dodge Road. The Sorensen Parkway runs west to North 90th Street as well; the street intersects I-680, as well as serving as the terminus of the North Freeway. U. S. Roads portal Transportation in Omaha
