|Build of Windows 3.0|
|OS family||16-bit Windows|
|Architecture||x86, PC-98, Fujitsu FM-Towns|
Windows 3.0 with Multimedia Extensions 1.0 (also called Multimedia Windows by some sources) is a special, multimedia-centric release of Windows 3.0, exclusively released on 20 October 1991 by various original equipment manufacturers (OEMs). Currently available releases include Tandy for the PC in English and German, an English release for the PC by Creative Labs, and Japanese releases for NEC PC-98 and Fujitsu FM-Towns.
It is the first version of Windows to support sound output and includes new programs for audio and video playback, including the first version of Media Player, new drivers for CD-ROM drives, sound cards, displays and joysticks and screensavers. The multimedia improvements were later incorporated into Windows 3.1. Although the operating system supports running in real mode, the new changes are only available in the Standard and 386 Enhanced modes.
Information from computer magazines[edit | edit source]
Another possible OEM release is shown and described in the November 1991 issue of Serbian computer magazine "Svet Kompjutera" (World of Computers). The boot screen shown in the magazine is different from the one in Tandy's release, referring to itself as Version 3.0 + Multimedia Extensions 1.0, whereas Tandy's release refers to itself as "graphical environment with Multimedia Extensions 1.0". The Tandy release uses both names during the installation process.
It is unknown if the version shown in the magazine is from a different OEM (see below) or a pre-release, as the magazine also calls it a "Multimedia Development Kit" (MDK).
Information from antitrust documents[edit | edit source]
An internal Microsoft document released during the Comes v. Microsoft antitrust hearings details the initial development plan for a "Multimedia Windows" release. According to the document, the alpha release was shipped to 35 external testing groups on 15 June 1990, with 25-30 additional sites to receive it on 1 August 1990. The beta release was to be released in mid-October 1990 and the final OEM Adaptation Kit (OAK) in December 1990.
Tandy is mentioned as the first OEM to launch their multimedia-capable PC-compatibles with Multimedia Windows. IBM, Fujitsu, Sharp, Olivetti, Zenith, Sony and Intel are listed as potential candidates for release. Microsoft Works for Windows with Multimedia extensions is mentioned as one of the apps to tie in with new features of Multimedia Windows.
New applications (Tandy OEM)[edit | edit source]
Windows Help[edit | edit source]
Windows Help in this release is version 3.07. The About dialog also states "Version 3.1.061d", which suggests this release has some files from pre-release versions of Windows 3.1 and implies Tandy released it shortly after build 061d was compiled.
Control Panel[edit | edit source]
About dialog says "Control Panel for Windows graphical environment with Multimedia Extensions 1.0" and "Version 1.0".

Problems and fixes[edit | edit source]
Display drivers[edit | edit source]
Certain newer graphics cards (like S3 ViRGE or Paradise) may not work as it could lead to display corruption upon loading the graphical interface.
Startup fix[edit | edit source]
Tandy has changed the default shell in their release to their application called FindCD (see above). This requires you to insert the installation CD, but the application often hangs at the start (possibly due to bad soundcard configuration) and you won't be able to get into Windows itself without changing the shell back to Program Manager in
To do this you must open the file
SYSTEM.INI in the installation directory, find the
[boot] section and change the line
shell=progman.exe. Windows will now start Program Manager on startup.
This doesn't apply to the non-Tandy versions since they set the shell to
PROGMAN.EXE by default.
Virtual PC Enhanced Mode fix[edit | edit source]
As this release is based on Windows 3.00a, it also requires a change to
SYSTEM.INI if you wish to run it in 386 Enhanced Mode in Virtual PC 2004/2007.
Other[edit | edit source]
Both Tandy and non-Tandy versions include special video drivers, including a 320×200×256 color driver, with special fonts, it works on any virtualization software that emulates a VGA card. It can also be used on later versions of Windows (up to Windows 95) by upgrading from this version.
