For those of you using Windows Azure, we finally have official PowerShell support for managing your Azure subscriptions. With the CTP release of the 1.7 SDK, you can install the Windows Azure PowerShell cmdlets. The download is here.
Keep in mind that this is a CTP, and the first version of the cmdlets released, so there are a few rough edges and missing functionality still. But they are already very usable and a big improvement if you need to manage more than a single image in Windows Azure. As I get time, I'll be posting more stuff here, but I also recommend you add Michael Washam's blog to your favourites.
