Signing out of Windows is the process of closing your session and ensuring that your account is no longer active on the device. This helps maintain the security and privacy of your account, as it prevents others from accessing your personal files, applications, and settings.
When you sign out, any open applications are closed, and unsaved work may be lost. It's always a good practice to save your work before signing out.
When should I sign out?
Sign out when you are done teaching in a classroom, or going home for the evening.
How do I sign out?
To sign out of Windows, select Start , select your user picture or the Accounts icon, and select Sign out.
