[SOLVED] Class Not Registered Windows PC Error Code Problem

The Explorer.exe Class Not Registered Windows PC error pops up whenever we are using applications with unregistered DLL Files. DLL Files are the dynamic link libraries that are mandatory for running an application program on your operating system. They are the Microsoft’s implementation of the shared library concept. These DLL files also contain instructions that other programs can call upon to do certain things. The unregistered DLL files hamper the request by the other programs to access them. This causes the error “Class not registered.”

Sometimes, the error also occurs due to incorrectly registered C++ classes in particular programs. This error usually occurs in Internet Explorer, File Explorer, and Edge browsers.

This shows an error code message like,

Class Not Registered

Explorer.exe Class Not Registered Windows

Also, when you are unable to receive a response to your click on the Start button with the left mouse click, or the search bar in the Windows Operating System doesn’t work correctly, these are also the symptoms of the error, “Class Not Registered.”

The class not registered error can hamper any of your application programs and can even ruin up your well-maintained Windows, so please beware of this problem and download only the legit software. It may be a Class Not Registered error in the standard C++ Libraries, or in the DLL files or maybe it’s due to the wrong installation of the Common Language Runtime Libraries (CLRs) in your system.
