Dear djsoa hudw,
Thank you for reaching out.
Let's walk through several troubleshooting steps to help resolve this issue. Based on your description, this might be due to cached settings, corrupted system files, or a configuration issue.
Please follow the steps below:
Step 1: Reset Windows Spotlight and Lock Screen Settings
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
- Disable Spotlight via PowerShell:
- Press Win + R, type powershell, and press Enter.
- Copy and paste the following commands one by one into PowerShell:
- Delete Cached Files Manually:
- Navigate to the following folder: C:\Users<YourUserName>\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets
- Delete all files inside this folder to clear any residual Spotlight images.
- Restart your PC and try changing the lock screen background again through Settings > Personalization > Lock Screen.
Step 2: Registry Tweaks (Optional – Advanced Users)
If the issue persists, let’s try a registry tweak to ensure the correct settings are applied:
- Press Win + R, type regedit, and press Enter.
- Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization
- If the Personalization key doesn’t exist, right-click Windows, select New > Key, and name it Personalization.
- Inside the Personalization key, right-click, select New > DWORD (32-bit) Value, and name it NoLockScreen.
- Set the value of NoLockScreen to 1.
- Close the Registry Editor and restart your PC to apply the changes.
Step 3: Perform an In-Place Upgrade (Repair Install)
If system files are corrupted and preventing the background from updating, you can perform an in-place upgrade to repair Windows without losing your data:
- Download the latest Windows 10 ISO from the official Microsoft website.
- Visit the Windows 10 Download page.
- Under Create Windows 10 installation media, select Download the tool now.
- Launch the Media Creation Tool and choose Create installation media for another PC.
- Select the ISO file and save it locally.
- Once downloaded, right-click on the ISO file and select Mount.
- Run the
setup.exeon the mounted drive. - During setup, choose the option to Keep personal files and apps.
- Follow the on-screen prompts to complete the recovery installation.
This process will repair any corrupt files that might be causing the issue.
Step 4: Create a New User Account
In some cases, user profile settings might be the root cause of the problem. To rule this out:
- Press Win + I to open Settings.
- Go to Accounts > Family & other users > Add someone else to this PC.
- Create a new local user account and log in with it.
- Check if the lock screen image behaves correctly under the new user profile.
Please keep your system updated and monitor if the issue improves after any future updates. If needed, feel free to reach out with further details, and I’ll be happy to assist you further.
