What command should be used to update policies on a Windows 10 computer without logging off?

The command used to update policies on a Windows 10 computer without requiring a logoff is "gpupdate." This command allows system administrators to refresh Local Group Policies and Active Directory Group Policies on the local machine. By executing it, you can ensure that any changes made to Group Policy settings are applied immediately, rather than waiting for the periodic background refresh or requiring users to log off and back on.

While "Shutdown" is a command used to power off a computer, it does not relate to updating policies. "DISM" (Deployment Imaging Service and Management Tool) is primarily for servicing and managing Windows images, not for updating policies. "Local Security Policy" refers to a management console where one can view or modify security policies, but it is not a command that updates those policies directly. Therefore, gpupdate is the appropriate command for this purpose.
