Windows 95 OEM Service Release 2 is version 950b of Windows 95. An OEM Service Release is an updated version of a product for PC manufacturers (OEMs) to preinstall on new PCs.

This product is Windows 95. It contains some new hardware support and programs, but at its core it is Windows 95. The purpose is to allow PC manufacturers (OEMs) to install an integrated Windows 95 product that contains the latest available individual updates and supports recent advances in hardware that requires core operating system support.

The retail version of Windows 95 is designed to upgrade Windows 3.x PCs. The primary contents of this service release are intended to support new hardware. As such, it will be sold with the PCs that have these new hardware capabilities. The only major feature that does not require specific hardware support is the new version of Microsoft Internet Explorer.

NOTE: A retail Windows 95 (version 950) installation cannot be upgraded with Windows 95 OSR2.

At this time, there are no plans to make these features available in a step- up, service pack, or upgrade kit for Windows 95.

Microsoft Internet Explorer version 3.0, and the individual updates that are widely applicable to a general audience will be available for free downloads from the Internet.

Microsoft reserves the right to revise and change these plans without notice.
