Windows Server 2012 R2 new install in Azure, with an odd behaviour: when loading an ISO file (right click in Explorer, select Mount), instead of mounting on the existing CD drive E:, it creates a new CD drive, on the first available letter, G:, and mounts it there. When I eject G:, it unmount the ISO and the drive just disappears from the list.
No other software installed, it's the stock February 2015 Azure image.
Looked at doing it via Powershell, but Mount-DiskImage doesn't have a parameter for the target drive or letter.
Any way to fix this ?
