OSR 2

Last Updated May 24, 2021 1:51 pm

Short for OEM Service Release 2, a new version of Windows 95 released at the end of 1996. Also called Windows 95b, OSR 2 provides a number of new features and bug fixes. Probably the most important new feature is FAT32, a new version of the file allocation table. FAT32 supports disk drives up to 2 terabytes and yields better storage efficiency due to smaller clusters.

OSR 2 is only available bundled in new computers. You cannot obtain it as an upgrade to older versions of Windows 95.
