Windows 3.1 did not introduce much of
anything new over Windows 3.0.
Windows 3.1, however, was the first really
widely used version of Microsoft Windows.
Windows 1 and 2 were heavily ignored or
viewed as little more than yet another
Even Microsoft's original intention
was to replace Windows 2.x with OS/2.
However, after IBM and Microsoft went
their separate ways Microsoft focused
on delivering Windows 3.x while
building their own new "Windows NT"
operating system, with the intent of using
Windows 3.x as a "stepping stone"
to get users to their NT based system.
This stepping stone lasted a little
longer than they wanted, going through
95, 98 and finally ending with
There was also a less common version
of Windows 3.1 bundled with Microsoft's
MS-DOS based networking software
named "Windows 3.1 for Workgroups".
Regular Windows 3.1 did not include any
networking software, but could run on top
of any DOS based network
such as DEC Pathworks, or
Microsoft Lan Manager.
An update, basically a service pack,
be applied to Windows 3.1 that brought
the version number up to "3.11".
"Windows 3.11 for Workgroups" bundled an

Windows 95 is a big successor of
to their Windows for Workgroups 3.xx.
It is no longer a graphic user interface
on MS-DOS, but a complete operation system.

The system box in the upper left of each
window is designed as an icon of the program.
In each window, the system box, "Minimize",
"Maximize/Restore" and "Close" are usually
located at the upper right corner.
In this version of Windows, desktop was
longer a place to display minimized icons.
Desktop now can not only store shortcuts and
system icons such as new introduced
"My Computer" and "Recycle Bin", but also
store files and programs.
Before Windows 95, Microsoft almost never
provided functions that could be accessed
by a right click in Windows system,
from Windows 95, right click pop-up menu
became more popular and important.
User could use right click to access
the functions of "copy", "paste" and "cut"
almost everywhere in the system.
Some functions such as "properties"
and quick "help" can also be accessed
Windows 95 came with an improved help
system, which added another window to
the left of the content window to show
index, and keywords.
The new help system can be displayed in
any place of the window with any kind
It also supported hyperlink with
different functions, such as
closing the help system.
Other features like Build-in network
support with dial-up for TCP/IP protocol,
support of 32-bit application, pre-emptive
multitasking and thread made
Windows 95 stronger to meet the
requirement of Internet access and
other complex tasks.

the original floppies were 8 inches wide

were really flimsy and "floppy" hence
