Windows/386 2.1 is an RTM build of Windows 2.x. This build is the i386-specific variant of Windows 2.1, which was enhanced with support for the virtual 8086 mode (MS-DOS applications could run simultaneously) and extended memory. It was marketed as "Windows/386" to denote it from the 286 variant. This is the first version to have Memset included with Windows.
