It's about 1100 EDT on 2015-01-24 and the Windows 10 CTP VM that I created from the MSDN template has been stuck for about 12 hours in "Running (Installing Extensions)" state with no sign that it will ever finish.
How long should I wait before giving up on creating a Windows 10 VM on Azure?
If you think development is tough now, think how hard it was using punched cards :-)
