  1. Class not registered (explorer.exe)


    I am going crazy at my laptop so if anyone can help I will be incredibly grateful.

    I will try to give you as much information as possible so you can narrow down the problem.


    I have a HP Stream x360 11.6" 2 in 1 Laptop. I have basic applications installed such as;

    Mail

    Facebook

    Microsoft Edge

    Baidu PC Faster


    4 days ago I attempted to access Facebook and the error "Class not registered" came up, the top of the error box said "explorer.exe"

    Feeling fairly confident I could fix this myself, I did the following things to attempt to fix it;


    SFC /Scannow in cmd

    Ive tried un-registering the Dll file for explorer, then Ive tried registering it again.

    Ive tried re-registering components in Component Services>Computers>My Computer>DCOM Config.

    Ive tried editing the regdll file to re-register all of the dll files which took over 2 hours)

    I tried setting my default apps but it wont allow me on it, I press it but nothing happens, and that happens with the Start menu as well. I cant get into apps and features like some google result said mainly because it doesn't exist, if it does exist it is called something else on this laptop.

    I have even tried booting it in safe mode and doing the cmd runs to see if that makes any difference.


    Any help will be much appreciated,

    Thank you in advance.

    From JayJay

  3. Class not registered for explorer

    Hi,

    Thank you for posting your query on Microsoft Community.

    I understand that you receive Class not registered error. We will help you to resolve the issue.

    I suggest you to try the steps below and check if it helps.


    • Press “Windows key + R” to get the run window.

    • Type “services.msc” and hit ok to open the services window.
    Scroll down to find “Internet Explorer ETW Collector Service” and ensure to have this service started and check if this helps.

    I also suggest you to perform SFC scan and check if it helps.



    System File Checker (SFC) is a utility in Microsoft Windows that allows users to scan for and restore corruptions in Windows system files. Perform System File Check (SFC), and then check if this fixes the issue.

    1. Press the Windows button + X on your keyboard, a mini dialogue box will appear.

    2. Choose Command Prompt (Admin). You must run the command prompt in Administrator level.

    3. On the command prompt type sfc /scannow and hit enter.

    4. If everything went okay and no errors were found, restart your computer and see if the issue re-occurs.

    Hope the information helps. Let us know if you need further assistance. We will be happy to help.

    Thank you.
