Back Up Your PC with Windows Backup
Windows Backup uses OneDrive to continuously back up your Desktop, Documents, and Pictures folders, along with your list of installed apps, saved Wi-Fi network passwords, and select personalization settings like your theme and wallpaper. It's designed to make restoring your setup on a new PC, or after a reset, far less painful than starting from scratch.
How to open Backup
- Open Settings → Accounts → Windows backup.
- Turn on folder backup for Desktop, Documents, and Pictures.
- Toggle whether to remember your apps and preferences.
- Check 'Manage sync settings' periodically to confirm everything is syncing correctly.
What you should know
- Enable folder backup for Desktop, Documents, and Pictures to sync them continuously to OneDrive.
- Choose whether to also remember your installed apps list and preferences for easier setup on a new PC.
- Backed-up settings restore automatically when you sign into a new or reset PC with the same Microsoft account.
- Check 'Manage sync settings' if backup appears paused or stuck.
This backs up specific folders and settings, not your entire drive — it isn't a substitute for a full image backup if you need to fully restore a PC from complete failure without reinstalling Windows.
Why it matters
Losing a laptop, having a drive fail, or simply setting up a new PC is far less stressful when your Desktop, Documents, and Pictures are already safely synced to OneDrive rather than trapped on a single failed or misplaced device. Remembering your installed apps and preferences also meaningfully speeds up getting a replacement PC back to a familiar, usable state instead of manually reinstalling and reconfiguring everything by memory. Because it runs continuously in the background once enabled, it protects you without requiring you to remember to manually back up on any regular schedule.
Best practices
- Enable folder backup for Desktop, Documents, and Pictures as soon as you set up a new PC, rather than waiting until after you've lost something.
- Check your OneDrive storage quota periodically, since backed-up folders count against your account's storage limit and large media libraries can fill it quickly.
- Don't treat this as a replacement for a full system image backup if you specifically need to restore an entire drive, including apps and system files, without reinstalling Windows.
- Verify sync status occasionally rather than assuming it's always running silently in the background without issues.
Common problems and fixes
- Folder backup shows 'Paused' and files aren't syncing.
- Open OneDrive from the system tray and check for a sync error, low storage warning, or paused state that needs to be manually resumed.
- OneDrive storage fills up quickly after enabling folder backup.
- Review what's inside Desktop, Documents, and Pictures for large files that don't need to live there, or upgrade your Microsoft 365 storage plan if you need more space.
- A new PC doesn't automatically restore your backed-up settings after signing in.
- Confirm you signed in with the exact same Microsoft account used for the original backup, and give it some time, since restoring installed app lists and preferences isn't always instantaneous.
Tips and tricks
- Right-click the OneDrive icon in the system tray for a quick view of current sync status and any pending issues without opening full Settings.
- Combine this with a separate full image backup tool if you want both convenient folder-level protection and a complete disaster-recovery option.
Frequently asked questions
Does Windows Backup back up my entire hard drive?
No, it specifically covers designated folders (Desktop, Documents, Pictures), installed app lists, saved Wi-Fi passwords, and select settings — it isn't a full disk image backup.
Do I need a paid Microsoft 365 subscription to use this?
A free Microsoft account includes some OneDrive storage sufficient for modest use, but larger folders will need a paid Microsoft 365 plan for enough space to back up everything.
What happens to my backed-up files if I stop paying for extra OneDrive storage?
Your files remain safe, but if you exceed the free storage limit, OneDrive stops syncing new changes until you free up space or restore paid storage.

More Storage & Backup guides for Windows
- Storage SenseStorage Sense automatically frees up disk space by deleting temporary files, emptying the Recycle Bin after a set number of days, and clearing out old files from your Downloads folder on a schedule you configure. Once set up, it runs quietly in the background so you don't have to remember to manually clean up disk clutter yourself.
- File HistoryFile History is a legacy Control Panel backup tool that continuously copies versions of files in your libraries, desktop, contacts, and favorites to an external drive or network location. Unlike a single backup snapshot, it keeps multiple versions over time, letting you restore not just a deleted file but an earlier version of one you've since changed.
