In this article, we will talk about how to Fix the RunDLL Error in C:\WINDOWS\system32\PcaSvc.dll Missing entry: PcaWallpaperAppDetect in Windows 11.
After the Update to Windows 11 24H2, Build 26100.712, some users have noticed a New RunDLL Error with the message Missing entry: PcaWallpaperAppDetect.
The fix for this is really simple, and the only thing that you need to do, is to Delete a Task from the Task Scheduler Library.
- Type “Task Scheduler” in the Search Box on the taskbar to find and open Task Scheduler.
- On the left of Task Scheduler, click on the Task Scheduler Library to expand it.
- Keep expanding the nodes in the following order: Microsoft -> Windows -> Application Experience.
- After clicking on the Application Experience node, find the task named PcaWallpaperAppDetect from the list view in the middle of Task Scheduler.
- Right-click on that task, click Delete in the pop-up menu. Then click Yes on the confirmation dialog box asking, “Do you want to delete this task?”.
