In some cases, uxtheme.dll errors could indicate a registry problem, a virus or malware issue, or even a hardware failure. However, these errors are usually seen because a theme patcher was used to customize a Windows theme or install unsigned themes, which changed and ultimately corrupted the DLL file.
