Note: UITS recommends that you use a current version of Windows on computers connected to the Indiana University network. For more information, see For Windows computers on the IU network, why does UITS recommend Windows 2000, XP Professional, or Vista Enterprise or Ultimate? Security features on the IU network prevent Windows 95, 98, 98SE, and Me computers from authenticating to ADS, printing to some network printers in departments and campus housing, and mapping drives to other computers.
OSR2 (OEM Service Release 2) was a service release of Windows 95 that Microsoft released in early 1997. It was not available for general retail, but was only available with the purchase of a new computer or hard drive.
