At the 2007 Consumer Electronics Show, Microsoft figurehead Bill Gates announced in his keynote speech a new Windows product, Windows Home Server. In retrospect that was a bad time to announce the product as it was in the critical period between Windows Vista having gone gold and being released at retail, so few people were interested in "that server product" as opposed to Microsoft's long-in-development successor to Windows XP. Since that point the Vista launch came and went, while there has been little noise from the Windows camp about Home Server.

If we had to sum up Windows Home Server in one word that word would be "strange." Even having gone gold and shipped to system builders and distributors, Microsoft has been strangely quiet about a product they're targeting for the consumer space - we still don't know quite when it will be for sale or at what price. The fact that it's even for sale unbundled with hardware, albeit only as OEM software, is itself strange as this was originally slated to be only sold as part of complete computers from the usual suspects among the computer vendors. Finally, as we'll see even as a product it's strange, and difficult to really come to terms with.

So what is Windows Home Server (WHS)? The name says it all and at the same time says nothing. At its core it's a server operating system designed for use in the home, a place that previously has not needed or been offered anything like a true server. That means that WHS really doesn't compare to any one thing; it's a backup suite, it's a file server, it's a network attached storage(NAS) device, it's a web server, it's a media hub, it's a computer health monitor, it's even a gateway for Window's Remote Desktop. In even trying to describe the product, we run into the same problem Microsoft does; it's one thing to describe a product as "X but better" but it's another thing entirely when we don't have anything to serve as a comparison.

Perhaps the easiest way to understand what WHS is, is understanding why it exists. Microsoft, never one to shy away from finding a way to sell another computer, has come to the conclusion that with the saturation of full computers and smaller smart devices in homes (where some households are reaching the point where they have two computers per person) that the time has come where not unlike a corporate environment households now need a server to keep everything in order.

But home users don't need the same kind of server that business users need. Home users won't be running or need to be running their own SQL server or email server, but what about centralizing the location of everyone's media files? Or a web server for letting the relatives see all your photos? Or a backup suite that actually backs files up somewhere else than to the hard drive of the machine in question? And how about something that doesn't require an MCSE certification to run? Over the last two years Microsoft has been once again retrofitting the Windows Server 2003 kernel (previously refit to serve as Windows XP Pro x64) to be the new server that can do all of the above.

The result of those two years of effort is a very interesting product that we'd consider the most interesting Windows product to come out of Microsoft since Windows 2000, and yet at the same time it comes with the quirks that are undeniably Microsoft. As we'll see WHS can offer a lot of value to the market Microsoft is shooting for, but can it overcome the difficulties of forging a new market, and fighting against its own deficiencies? Let's take a look under the hood of Windows Home Server and find out the answer.
