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.

DLL files, or dynamic-link libraries, are essential to operating all Windows programs. These files benefit users because they require less memory and may perform their functions without being loaded together at once.
