So with this being the case, just manually changing the system date to an earlier date will not solve the problem. For this purpose there is a small Tool known as RunAsDate.
RunAsDate is a small utility that allows you to run a program in the date and time that you specify. This utility doesn’t change the current system date, but it only injects the date/time that you specify into the desired application.

RunAsDate intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify. It works with Windows 2000, XP, 2003 and Vista.
