Easexp Settings Backup (ExSB) is a tool to back up, restore, sync Windows system settings such as date time, formats, wallpaper, colors, taskbar, group policy, firewall rules, disabled services, tasks, events...and the settings of popular programs such as Office, Firefox, Edge, Chrome etc.
ExSB is not designed for backing up common files, although it's able to. You can consider ExSB to be like the Windows Sync, only it's a real backup tool that can save those settings in files or folders, and restore them to system at any time you want.
