Copy every photo to a folder or external drive outside OneDrive and verify that copy before stopping backup or unlinking the PC.
1. Preserve the photos first
Do not delete photos from the OneDrive folder yet—while synchronization is active, deleting a synced file can also delete it from OneDrive and other connected devices.
- Confirm the PC or an external drive has enough free space for all the photos.
- Open File Explorer → OneDrive → Pictures.
- Right-click Pictures and select Always keep on this device.
- Leave the PC connected to the internet and power until every photo has downloaded. A blue cloud means the item is online-only; a solid green circle with a white check means it is stored on the PC. ^1^
- Create a separate folder that is not inside OneDrive, for example:
-
C:\Saved Photos, or
- a folder on an external USB drive.
- Copy, rather than move, the photos into that folder.
- Open several copied photos, compare the folder/file counts, and ideally make a second copy on another external drive.
If Windows reports that some files could not be moved because they are cloud-only, they have not finished downloading. Keep them set to Always keep on this device and wait before continuing. Microsoft specifically requires cloud-only files to be downloaded before folder backup can be stopped while retaining them locally. ^2^
If the PC lacks enough space, download the photos in batches from OneDrive on the web directly to an external drive. Being over quota makes existing files read-only, but downloading or deleting them remains available. ^3^
2. Stop OneDrive from backing up Pictures
After verifying the independent copy:
- Select the OneDrive cloud icon near the Windows clock.
- Select Help & Settings (gear) → Settings.
- Open Sync and backup → Manage backup.
- Turn off Pictures. Also turn off Desktop or Documents if you do not want those folders stored in OneDrive.
- When prompted, select Keep the files only on my PC.
That option removes the folder’s OneDrive copy, so select it only after the separate copy has been checked. ^2^
3. Disconnect OneDrive
Once the photos are safely outside the OneDrive folder:
- Select the OneDrive cloud icon → gear → Settings.
- Open Account.
- Select Unlink this PC → Unlink account.
Unlinking stops synchronization and does not itself delete data from the computer or OneDrive website. ^4^
Optionally uninstall it afterward through Settings → Apps → Installed apps → Microsoft OneDrive → Uninstall. Do not erase the old OneDrive folder until the independent copies have been verified.
Important deadline
For a personal Microsoft account, OneDrive becomes frozen after three months over quota, and after six months Microsoft might delete the OneDrive and all files permanently. ^3^ Treat the January date shown in the account warning as the working deadline.
After securing the photos, remove unwanted cloud copies and empty the OneDrive Recycle Bin, because recycle-bin items also count toward the storage limit. Do this only after confirming that the PC/external-drive copies open correctly.
