Creative 900 ユーザーズマニュアル

operating system when applications are being installed.
At the time of this product's release, Microsoft strongly encouraged companies to 

submit their hardware solutions for certification. If a hardware device driver is not 

submitted, or does not qualify, for Microsoft certification, a warning message similar 

to the one below appears.

You may see this message when installing a  driver. If you do, you may choose to 

click the Continue Anyway button. Creative has tested the driver on Windows XP, 

and it does not impair or destablize your computer.
