Windows Backup can remember selected folders, settings, Wi‑Fi information and some apps using a personal Microsoft account. It is useful, but it should not be your only copy of irreplaceable files.
1. Identify what matters
Start with Documents, Desktop, Pictures, Videos and any work folders stored elsewhere. Do not assume a file is backed up just because it is visible on your PC.
2. Open Windows Backup
Open Start, type Windows Backup and select it. Sign in with a personal Microsoft account if requested. The service uses OneDrive storage for selected folders, so check that you have enough available space.
3. Choose folders and settings
Expand Folders and choose the folders you want to protect. Review the options for apps, preferences and Wi‑Fi information. Only enable what you are comfortable synchronising to your Microsoft account.
4. Make a separate copy of big files
For large photo libraries, video projects or archives, copy them to an external drive as well. Label the drive and keep it disconnected when not in use, so one hardware problem or malware incident is less likely to affect both copies.
5. Test your backup
Open OneDrive or the external drive and confirm that a recent file is present and readable. A backup you have never checked is only a hope.
