Virtual desktops are of two types: Persistent and Non-Persistent desktops. Persistent Desktops- In this, you can save all the settings or configurations as you desire. All the information is stored on the operating system. Hence, it requires more storage space which increases cost as well. However, when you log back in, your information remains the same as when you left while logging off. Non-Persistent Desktops- In this, none of your information or settings is retained. Hence, it requires less storage space and cost. However, the next time you log in to the desktop, you will not get the saved information. Each session will start fresh.
