@Daniel Nascimento Thank you for your query!!!
Azure Virtual Desktop supports the complete range of experiences including full desktop virtualization and application virtualization, persistent and non-persistent states as well as dedicated and multi-session modes.
Persistent virtual desktop infrastructure (stateful VDI) is a setup in which each user owns a virtual desktop whose settings and customizations are available to the user each time they log in. The consistency of user experience and familiarity with the customizations help users get accustomed to these virtual desktops faster.
In the case of non-persistent VDIs, the data and settings on a virtual desktop are erased at the end of the session. Users will have a new image when they begin a session.
The primary advantage of a non-persistent VDI is that it requires much less space and is more easily managed. The ephemeral nature of the non-persistent VDI makes it an ideal solution for tasks that require more security.
Hence in Persistent VDI user data is retained. You can refer to this for more information.
Hope it helps!!!
