An Azure service that is used to provision Windows and Linux virtual machines.
If your VM keeps booting into Safe Mode, the Safe Mode flag may still be set in the Windows boot configuration.
You can remove it by opening Command Prompt as Administrator and running:
bcdedit /deletevalue {current} safeboot
After that, restart the virtual machine and it should boot normally.
