Windows for Workgroups Ver.3.11 © 1993 Microsoft
Windows for Workgroups 3.11 supported 32-bit file access, full 32-bit network redirectors, and VCACHE.386 file cache, shared between them. WFW 3.11 dropped standard mode support and requires a 386 machine to run.
Released on August 11, 1993 and shipped in November 1993.
Originally codenamed Snowball.
Following the release of MS-DOS 6.22 in 1994, WFW 3.11 largely replaced Windows 3.1 for OEM installations on new PCs due to its improved capabilities and greater stability.
