when I try to open a picture file.a grid comes up,cant load photo.error message 0x800701AA.also some pictures in my photos hav a black screen

Error 0x800701AA indicates that Windows timed out while retrieving a cloud-stored file, so first identify whether the affected picture is in OneDrive, iCloud Photos, Dropbox, or an ordinary local folder, then use the matching steps below.^1^

1. Identify where the picture is stored

1. Right-click an affected picture and select Properties.
2. Check Location:
   • A path containing OneDrive: follow the OneDrive section.
   • A path containing iCloud Photos: follow the iCloud section.
   • Another cloud provider: use that provider’s download or offline-availability option.
   • No cloud folder, and no cloud icon beside the file: skip to Test the local file.

Do not delete the affected pictures while troubleshooting; deleting a OneDrive file can also delete its cloud copy from other devices.^2^

2. If the pictures are in OneDrive

A blue cloud icon means the picture is online-only and has not yet been stored completely on the PC.

1. Confirm that the PC is online and OneDrive is signed in.
2. In File Explorer, right-click the affected picture—or its folder—and select Always keep on this device.
3. Wait until its status changes to a green circle with a white check mark. This means OneDrive downloaded a local copy.^2^
4. Open that picture again.

If the download remains stuck:

1. Select the OneDrive cloud icon in the notification area.
2. Check for a displayed sync, sign-in, or storage error.
3. Apply the matching action from Microsoft’s OneDrive sync troubleshooter.^3^
4. If no specific error resolves it, use Microsoft’s supported Reset OneDrive procedure, then allow synchronization to finish before testing again.^4^

3. If the pictures are in iCloud Photos

For an iCloud placeholder that will not download:

1. Open Start → Settings → Windows Update → Check for updates.
2. Install all offered Windows updates and restart.
3. Open Settings → Apps → Installed apps → iCloud → three dots → Advanced options.
4. Select Repair, then test the picture.
5. If Repair does not work, return to the same page and select Reset.
6. Sign in to iCloud again if requested and let the picture download before opening it.

This sequence has been used for the same error when iCloud’s cloud-file download process is stuck.^5^

As a temporary recovery method, download the original picture from the applicable cloud service’s website and save it into a normal local folder.

4. Test the local file, then repair Photos

After the file has downloaded—or immediately if it was already local:

1. Right-click the picture and select Open with → Paint.
2. If Paint also shows black or cannot open it, the problem is with that file or its incomplete download. Download the original again or restore it from a backup.
3. If Paint displays it correctly but Microsoft Photos does not:
   • Open Start → Settings → Apps → Installed apps.
   • Find Microsoft Photos and select three dots → Advanced options.
   • Select Repair and test again.
   • If that fails, select Reset. Reset clears the app’s settings/data but does not delete the picture files.^6^

If only .HEIC or .HEIF pictures are black and Photos asks for an extension, install the HEIF/HEVC extensions described by Microsoft, then restart Photos.^7^
