I have recently switched my laptop over to Windows Server 2008 from Windows 7 to take advantage of hyper-v. I wasn’t happy with Virtual PC 2007 for Windows 7 and VMWare is too expensive when I have access to Windows Server 2008. Overall the experience is very good as Windows Server 2008 runs very quickly on my Lenovo t61 (I am not running the Desktop Experience feature as this sucks too many system resources). Since I am running this machine as my core workstation I am running Office 2007. I ran into a scenario where I wanted to enable Outlook Instant Search. Here is a link to a good blog post that walks you through the process of enabling Outlook Instant Search on Windows Server 2008.
