Windows 7 Testing and Ecosystem Interoperability


This week marked the availability of Windows 7 to consumers worldwide. The operating system is being touted as a vast improvement over its predecessor, Windows Vista. One item that Microsoft focused intensely on when developing Windows 7 was user experience – providing a smooth, snappy and bug free experience for its customers.
So what steps are necessary to deliver a positive experience across the millions of possible PC configurations in the marketplace?
Earlier this summer, we detailed the
Windows Logo Program. This program, primarily for hardware manufacturers, ensures that systems and devices will function properly with Windows operating systems (Windows Server® 2008 R2, Windows Server 2008, Windows Vista and Windows 7). It also signals to consumers that the product has been tested to verify it meets Microsoft standards for Windows compatibility. This is essential as consumers worldwide load their new Windows 7 discs into millions of PCs from hundreds of manufacturers. What could be a compatibility nightmare appears to be a smooth transition that is bolstering Microsoft’s position in the market. To further ensure that consumers do not run into any roadblocks while making the transition to Windows 7, Microsoft has enhanced the requirements to receive a logo for Windows 7 hardware.

A new requirement mandates that firms seeking a Windows Logo first secure a USB certification. USB certification is a critical certification in the PC industry, and it will minimize the chance of a consumer’s USB device not performing as anticipated with the Windows operating system. The new policy is critical for hardware vendors and system manufacturers, who are preparing to submit their USB devices and systems for Windows Logo Program submission.
Simply stated, any devices (webcams, keyboards, mice) or hosts (desktops, laptops or netbooks) seeking a Windows logo must first receive certification from the
USB Implementers Forum. This certification guarantees compliance to the USB standard and in turn, promotes the greatest level of interoperability between USB hosts and devices.
For consumers, this new requirement is an important step. It will ensure that purchased devices carrying the Windows and certified USB logos will work as expected with their PC bearing the logos.
