This article was previously published under Q156492
When you are running a program or using a device driver that calls MMX- specific instructions in the retail release of Windows 95 on a system with an Intel processor supporting the MMX instruction set, the following symptoms may occur:
The retail release of Windows 95 does not properly support some MMX instructions if they are called from a device driver or from program code running in protection level 0 (Ring 0, also known as privileged or Kernel mode). If these instructions are issued while the processor is operating in Ring 0, a GP fault or other serious error may occur.
This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows
