How to fix “WMVCore.DLL is missing” error
Upon upgrading Windows 10, you may get a lovely error about WMVCore.dll being missing.
Alternatively, you may get the same error when trying to load a particular program.
The short version is that WMVCore.dll is a key component of the Windows Media Library.
It’s a file that more or less allows playing media files.
Fortunately, it’s pretty easy to restore this missing file and get back on the road!
