Yamaha XG WDM Driver for XP

Before, whenever I want to play an XG midi file, I would change our system date back to 2000 so my Yamaha S-YXG50 would work. This is not only inconvenient but it sometimes messes up our dates whenever I change the system date.

I have been searching for an alternative until I stumbled upon this forum thread: http://vogons.zetafleet.com/viewtopic.php?=&p=98293

It says the there is a WDM XG Driver for XP available from Microsoft. I had heard it before and searched the Windows Update Catalog but found nothing. The forum thread above provided the actual links to the WDM driver.
