Repair invalid wldcore.dll Registry Entries

Sometimes when installing, uninstalling or changing apps, there might be leftover entries in the Windows Registry. This is true in the case of Windows Live as well. 

Because of several apps sharing the wldcore.dll file, its registry entry might become corrupted or invalid as your apps change. Even if you have the file stored on your computer, its path might still point to an old, now nonexistent folder in the registry.

You can fix this by repairing the entries with the Registry Editor or downloading a trustworthy registry cleaner.

Note: Unless you have experience with computers, we don’t recommend editing the registry manually. While it is possible to fix the error via manual editing, it’s much more complicated than regular value editing.

Incorrect use of the Registry Editor can lead to even bigger errors in your system. We recommend automating the process due to the high risk of damage.

Here are some of the most trusted and easy-to-use registry cleaner applications to help you fix the missing wldcore.dll error:

  • CCleaner
  • Advanced SystemCare
