With the recent RTM release of Windows 7 and Windows Server 2008 R2 on July 22, I have updated all my desktops and laptops to Windows 2008 R2, so far no driver issues on any machine (How to upgrade your laptop/desktop to Windows Server 2008 R2?).
One thing I could not figure was how to display a preview of pictures using Windows Explorer and other visual effects that are standard with Windows 7.
Thanks to a Microsoft colleague the solution is simple, go to System Properties –> Advanced –> Performance Settings and check Show thumbnails instead of icons and voila!
With so many developers turning to Windows Server 2008 (R2) as their workstation, why doesn't Microsoft offer a developer-tuned SKU? Hyper-V is not just for server operations, it's a development essential!
you can purchase preconfigured laptop with W2k8 (not R2 yet) from Dell + you can also use the MSDN route
