Image is not up to date
You will need to update the software and do at least 1 reboot (maybe two). Then you will be unable to update Visual Studio because "some file is locked". Pretty disappointing that it isn't updated to the latest version of VStudio 2019 when you get it. Especially considering the price/hour to use the thing.
Thanks for the feedback. Visual studio or the Image doesn't require you to reboot. As known to any windows admin, reboots are required by windows update and like any image to avoid any zero day vulnerability, windows update are on to ensure you have latest security updates. Similarly for VS updation, It is required to exit VS else it shall give files locked warning. Again this is not the issue of the image but how any MS products updation works. Any version of VS and Windows is available from the publisher and there is no lock-in, so one can move from earlier versions to an latest version seamlessly or request from 24x7 support to help with any upgradation or downgradation.
