First, make sure that all the computers or tablets where you have used Windows use the same Microsoft Account. To confirm if the device you are logged in, go to Settings > Accounts > Sync your Settings, and see if you see a message which says: We won't sync Sign-in info to help protect your personal information unless you confirm this PC is trusted. Confirm this PC. When you click on the Confirm this PC, it will open your account settings and show you a list of devices you need to confirm. Once confirmed, your settings will sync for that PC. Once confirmed, select the list of settings you want to sync. It includes themes, Passwords, Language preferences, Ease of Access, and other Windows settings. If you want to sync passwords, you need to verify your identity.
