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.

Look thru that window.

Windows crashed on me again.

A time when a person is able to poop.
"Oh my God, I've got a window to take a shit right now. Wait, nope. It just crawled back up. I'll have to wait for the next window to come around."

The space of time associated with the most efficient opportunity to poop. Refers to both time that is convenient (opportunity) and sense of urgency to dump. Pooping before or after the window usually results sub-par pooping amount or satisfaction.
"I better go take a dump now, I don't want to miss my window."

Windows is a complicated armed forces code which really means "Dead on Site". "Dead on Site"'s acrynym is DOS and since DOS is linked to Windows they recoded it to Windows.
-"Base to CRO ((Cheif Radio Operator)), what's the TC ((tent city, code for prison camp)) look like?
-"CRO to base, we have 10 POWs who've gone through the Windows, 5 with a pal ((code for mal pal which is code for malaria)) and five friends of Jack ((Hungry Jack meals are prized possessions so friends of Jack would be people starving)).

An operating system created by the Microsoft Monopoly. They are only after taking your money adn screwing over your computer at the same time. O.. but I forgot.. they issue patches... and then they make more patches.. and then they make more patches... and so on and so fourth so that you think you are realy improving your computer when all your doing is updating the problem. Prefer an etchasketch over a PC running windows. Hell.. even Microsoft doesent even run a version of Windoze on their servers.
"O.. you run Windoze?....O God I'm so sorry..."

Something really crap, useless, or that doesn't work properly. Possible synonym for mindfuck.
OMG, did you see Leeds United last night on Match of the Day? They were really Windows!
