Once the software is installed, the configuration process is where the true utility of OneDrive begins. Upon launching the application for the first time, users are prompted to sign in with their Microsoft account. This links their local machine to the cloud. The setup wizard then asks the user to choose which folders to back up, including the ubiquitous Desktop, Documents, and Pictures folders. This feature, known as "PC folder backup," is one of the most critical aspects of the Windows 10 OneDrive experience. It ensures that if the computer is lost, stolen, or damaged, the user’s most vital files are automatically preserved in the cloud, ready to be restored on a new device with minimal effort.
