Azure Virtual Machine OS Disk deletes all the data

When I rebooted my virtual machine, I noticed that it takes a long time to redeploy, but wait a minute. After I logged in, it asked me to set up Cortana as a fresh install, and it also removed all the software and files on the operating system disk. It seems that it was formatted or that I was assigned a completely new disk but it did not ask me for any authorization, error or notification, I just delete everything, I need to recover the files that I had on the disk. They weren't on the Temporary Drive, they were directly on C.

IIf yes, then this behaviour is by design and unfortunately any data stored on the OS disk is lost.
