1. Run SFC and DISM
The problem could be due to corrupted system files. Running the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) utilities is recommended to address this. These tools scan for corrupted files, perform repairs, and restore system integrity.
2. Use Program Compatibility Assistant
The Program Compatibility Assistant is a built-in Windows service that helps in running older programs on newer devices. Running it will scan the issue and fix it, which might help in solving the problem.
3. Perform a Clean Boot
Third-party services can interfere with system files and cause issues. To determine whether they are causing the issue, try performing a clean boot of Windows. A clean boot stops all non-Microsoft services from running at startup, which might resolve the problem.
4. Delete Third-Party Wallpaper Services
If you have any third-party wallpaper services installed like Wallpaper Engine, Lively, etc., they can interfere with the system and stop it from working. To fix this issue, you can uninstall all the third-party wallpaper services.
5. Use Task Scheduler
Task Scheduler is a Windows utility that is used to stop Windows routine tasks. You can delete the PcaWallpaperAppDetect task using Task Scheduler, and Windows will not allow it to launch during startup.
6. Uninstall Update
If none of the solutions work, you can uninstall the update. This issue is caused by the recent 24H2 update, and uninstalling it will roll back Windows to the previous version and solve your issue. You can check our article on how to Uninstall Windows Update.
