Which Windows feature allows access to files and applications from multiple devices?

Microsoft OneDrive is the correct choice because it is a cloud storage service that enables users to store files online and access them from multiple devices. This feature is particularly beneficial as it allows for the synchronization of files, making them accessible whether on a laptop, desktop, tablet, or smartphone, as long as there is an internet connection.

OneDrive also integrates seamlessly with Windows, allowing users to save documents directly to the cloud, share files easily, and collaborate with others. The ability to access and manage files across various devices enhances productivity and provides convenience for users who work on multiple platforms.

The other options do not provide this capability. Windows File Explorer is primarily a file management tool used to navigate and manage files stored on a local device. Task Manager serves as a system monitoring tool, allowing users to view and manage running applications and system performance. Control Panel is used for configuring system settings and preferences but does not facilitate file access across devices.
