  • Hi,

    Given current condition, I advise you command to register the DLL file firstly to see if it can fix this issue.

    Please call out Task Manager and hold Ctrl when you click new task(Run) to open Command Prompt, then, type:

    cd \windows\syswow64

    regsvr32 c:\filename.dll

    sfc /scannow

    If the issue still persists, we suggest to restore the original Windows files since to change each one will cause the unstable things.

    Please go to C:\Windows and C:\Windows\System32 to recover your old Explorer.exe and ExplorerFrame.dll, delete those that you downloaded from other website.

    Then, call out Task Manager and create a new task named explorer.exe to see the result.

    After above operations, restart your machine to test result.

    In addition, check if the issue persists in safe mode, restart the computer and press and hold F8 key to enter safe mode. We could also execute system restore in the safe mode.

    In fact, we don’t suggest to change system components, if you want to change an aesthetically theme, change it directly.  

    Hope my clarification is clear.

  • There are certain system components that are not to be changed, for smooth working of Windows. Explorer is one such program. If you want to change the visual appearance, you can change the themes, rather than changing explorer or its components.

    Hence, rename the files back, restart the PC and then check. Follow the instructions:

    1. Press Ctrl+Shift+Esc. This will open Task Manager.

    2. Now, press File -> New task, holding Ctrl to open Command Prompt.

    3. Now, navigate to the location where you renamed the files and rename the files.

    4. Once done, type the command shutdown /r /f and press Enter. This will restart Windows.

    5. Check if desktop icons/taskbar loads on restart.
