Fast user switching is a feature in computer operating systems that allows multiple users to quickly switch between active user sessions without logging off or closing their applications. It enables simultaneous user accounts to remain logged in while another user account takes over the active session on the same computer.
When fast user switching is enabled, each user account retains its state, including open applications, documents, and settings. The active user's session is temporarily suspended, and the user is logged out without closing any running programs or files. The new user is then able to log in, and their session becomes the active one.
This feature is particularly useful in multi-user environments like shared computers or workplaces, where individuals need to access their individual accounts without interrupting other users' sessions. It provides a quick and seamless transition between user accounts, eliminating the need for time-consuming log-off and log-on procedures.
Fast user switching also enhances security by restricting access to other users' accounts, avoiding the risk of unauthorized access or tampering of in-progress work.
Furthermore, it enables the efficient sharing of one computer by multiple individuals, promoting collaboration and productivity. Users can switch back and forth between accounts, keeping their work or applications running without disruption, while other users can access their own accounts and perform their tasks.
