MORE INFORMATION

FAT32 file system support for Windows 95 is available in Original Equipment Manufacturer (OEM) versions of Windows 95.

Retail versions of Windows 95 cannot be upgraded to OEM versions, and there is no separate download to enable FAT32 support in retail versions of Windows 95. If you have an OEM version of Windows 95 that does not have FAT32 support, contact your OEM.

If you are running an OEM version of Windows 95, the Product ID number under the Registered To heading typically contains 20 digits. If digits 6, 7, and 8 contain the letters "OEM," your version of Windows 95 is an OEM version. For example, the following sample Product ID number indicates an OEM installation:

OEM Version Identification

Windows 95 may have been preinstalled on your computer. These installations are referred to as OEM installations. An OEM Service Release (for example, OSR2) is an updated version of a product for PC manufacturers (OEMs) to preinstall on new PCs. This allows OEMs to install an integrated Windows 95 product that contains the latest available individual updates and supports recent advances in hardware that require core operating system support.

Additional OEM Information

• In Windows 95 OEM Service Release 2 (OSR2), 2.1 (OSR2.1), and 2.5 (OSR2.5), not all files have the version stamp that is listed in the table. In OSR2.1 and OSR2.5, only files that were updated to provide support for the Win32 Driver Model (WDM) and Universal Serial Bus (USB) may have this version stamp. The other files have the same version stamps as the corresponding OSR2 files.
  
  You can view file version information by right-clicking a file in Windows Explorer, clicking Properties, and then clicking the Version tab. If there is no Version tab, there is no version information available for that file.
• Updates to Windows 95 OSR2 generally have a version number of 4.00.1112 or later.
