PRODUCT :Windows NT
PROD/VER:4.0
OPER/SYS:WINDOWS NT
KEYWORD :kbbug4.00 kbfix4.00

The information in this article applies to:

SYMPTOMS
========

An internal function within Mfc40.dll is designed to add 1900 to every 2-digit
date that is passed to it. For example, 99 is returned as 1999. If more than 2
digits are passed, nothing is added. Programs that use this function may
incorrectly parse a date after the year 2000 (for example, January 1, 2000, may
become January 1, 100).

This problem has been observed with the following applications:

 - Microsoft System Information (Msinfo32.exe)
