Just a quick scream out into the void…
You know when you build a new server, a real one, you get to choose what locale / regionalisation / language settings you want the server to be installed with?
How are you supposed to do that with Azure VMs built from the provided image library?
Unfortunately, it doesn’t appear to be as straightforward as it should be. I found this Feedback ticket on the Azure Forums: http://feedback.azure.com/forums/216843-virtual-machines/suggestions/6197573-set-locale-on-creating-vm
<Insert rant on middle-endian date formats and the lack of take-up of ISO-8601>
Please, all you non-US Azure VM users – go and vote it up!
