Additional Details About the “Explorer.exe Class not registered” Error

This issue implies that system files associated with ‘explorer.exe’ have become corrupted or gone missing, as stated in the error message. To truly understand this problem, we must first know the role and significance of a DLL (Dynamic Link Library) file in the Windows operating system.
