New old stock and sealed package vintage Microsoft Windows for Workgroups 3.11 with Certificate of Authenticity 1994. Per wikipedia version 3.11 was released with DOS 6.22. Important: The package does not specifies the media type but per the shape of the media I measured 3.5 floppy disks.
Note that the sealed plastic has an opening in the front but it is not big enough to get anything out of the package.  It 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.A Winsock package was required to support TCP/IP networking in Windows 3. Usually third-party packages were used, but in August 1994, Microsoft released an add-on package (codenamed Wolverine) that provided TCP/IP support in Windows for Workgroups 3.11. Wolverine was a 32-bit stack (accessible from 16-bit Windows applications via WinSock Thunk), which gave it superior performance to most of the third-party TCP/IP Windows stacks available. However, it was only compatible with Windows for Workgroups 3.11, and lacked support for dial-up. 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. Compatibility with Microsoft Windows NT Advanced Server, Novell NetWare, and Banyan Vines. Conditions: Sealed old new stock. Check out my other items.
