Using build 7100. Zboard worked fine before the update, and now the multimedia buttons at the top wont do anything. How do you uninstall this particular update? It's not listed in the installed updates, and I cant find it in the Add/Remove Programs either. Also, upon viewing the details in the update history, i get this Info: Ideazon - Input - Ideazon Zboard MM USB Human Interface Device Installation date: 5/11/2009 8:41 AM Installation status: Successful Update type: Optional Ideazon Input software update released in July, 2007 More information: http://winqual.microsoft.com/support/?driverid=20069969 Help and Support: http://support.microsoft.com/select/?target=hub If you follow that first link, you will see that it doesn't exist. Great job Microsoft..
