One of several pieces of software from Microsoft:

1. Windows 1.0 was a graphical shell that allowed the user of an IBM PC to have several MS-DOS programs running at the same time, sharing the screen through viewports called "windows," hence the name. It was released after the first Apple Macintosh computer, and most users did not install it because it required too much memory. MS-DOS was an operating system that could only have one application open at any given time, and those applications could only access up to 640 kilobytes of RAM. Files stored by it had names consisting of eight characters, a dot, and three more characters, and certain characters, such as spaces, were not allowed. TEXTFILE.TXT was a typical DOS filename.

2. ~ 3.0 was a graphical shell that also had dynamic library support, a feature normally built into an operating system. Applications had to be written "for" ~, almost as if it was an operating system. It did things on behalf of applications, like an operating system. It was started from DOS as an application, and exiting ~ returned the user to DOS. Instead of folders, there were program groups, where programs had to be explicitly placed. Placement of a program in the Program Groups typically involved telling ~ the complete path to the program executable (ie, "C:\COREL\WP.EXE")

3. ~ 95 was a graphical shell that was booted directly by DOS, so that it appeared to be the entire operating system. It imitated the look and feel of a Macintosh. It was capable of running most ~ NT binaries, and it implemented pre-emptive multitasking, a feature commonly found in operating systems, and added support for "long filenames" (LFN), which allowed files to have Macintosh-like names. The "Restart in DOS mode" feature is equivalent to the "Exit Windows" feature in older versions of ~.

4. Windows NT ("New" Technology) is a real operating system that was written completely independantly of the line of graphical shells that are also called Windows. Microsoft hired the employees of DEC that designed VMS to work on ~ NT. Unlike ~ versions that were already on the market, ~ NT took full advantage of the Intel 386's 32-bit capabilities. Its design was so closely tied to the Intel 32-bit architecture that it could not be ported to a 64-bit platform easily.

The "New" technology in ~ was new only to Windows. Features new to NT, such as true multitasking and virtual memory, had been available in other operating systems since the 1970s and even before that.

Microsoft eventually began to market Windows NT as an alternative to UNIX, but they did so at the same time that Linux was becoming ever more popular as a UNIX replacement. Windows NT had many bugs of its own, and its superficial similarities to Windows 95 caused users to expect Windows 95 bugs to be present in Windows NT. Its Internet server offerings were notably inferior to the UNIX programs they were meant to replace.

All current versions of Windows are descended from Windows NT, and not from the DOS shells that were also called Windows.

Though 64-bit Intel processors are already available in 2004, a 64-bit version of Windows is still years away.

Plates of glass. When used in a house, it can be opened for fresh air or in case of an emergancy.

A highly effective virus that spread itself by the using of instalations, saved in licensed Compact Discs, mostly instaled in the drive C:, no antivirus is available at the moment, but the method of formatting works very well.

approximately 70% of the population have infected computers with this virus... and counting...
fook !! my pc has windows xp !!!!!!!!

Glass panes common in the walls of buildings, especially sky scrapers, allowing people inside to see the outside and to let light in.
Windows have been around for thousands of years, although they were originally just holes in the walls of buildings, without any glass panes.

Windows should not be confused with the remarkably unstable and virus-susceptible Windoze.
Yesterday, I was wondering if it was raining or not, so I looked outside through the windows and saw that it was, in fact, raining. Without my windows, I could have gotten wet.

1. An opening or a panel built into a wall, roof, or floor inside structure to permit the pass through of light or air.

2. implies Microsoft Windows. A computer operating system developed by Microsoft. First released in 1985, running on top of MS-DOS, in order to implement a graphical user interface (GUI) computing.
"dude, I am suffocating!!"
"well, open the fucking windows!!"

"hey man, there are these faggots arguing about Windows vs. Linux again..."

A shitty operating system modeled after a good operating system that did the same things 10 years earlier.

An operating system that is quite easy to install and use. Crashes more often than not ('98 does anyway), but is generally a nice OS for people who want to use a computer AND have a life outside of the house at the same time.
Windows just crashed so I threw my PC out of the window.
