Windows 3.x was the first to gain significant development and commercial traction. It combined the 8086, 286, and 386 modes of Windows 2 in to one package. It replaced the MSDOS Executive with a Program Manager and File Manager similar to those in OS/2 1.x. Much of its success was spurred by the availability and success of Microsoft Office. Although Microsoft would have had you believe otherwise, Windows 3.x was the direct foundation for Chicago/Windows 95.
Other Windows Versions:
| 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |
Windows for Workgroups 3.1 was the lesser known first release of the "For Workgroups" product. This version bundles an earlier 386-protected mode networking stack with Windows 3.1. This version does not support TCP/IP.
