Windows 10: Class not registered and start menu does not show

I have tried the task manager solution but in task manager the task were hidden and could not apply the fixed described on the community. Even tried the command prompt as an administrator but I could not get into the command prompt as an administrator.


What worked for me is to use component services by typing windows key and R, get into the run window and type dcomcnfg click OK.

a Windows will open, called Component Services.

You need to go into Component services>computers>mycomputer and double click on DCOM config.

Once double click there are few warning messages that will open but just say yes to each one.


once completed close the component services window and restart the computer.


Now start menu is working and Explorer as well as the set up menu does not produce anymore the class not registered.


Go on the following link to have all the possible solution:

Can anyone help me out here?

Class Not Registered Error

Hi,

There are different factors that can contribute as to why the quick link menu (Windows key + X) and the Start menu in Windows 10 are not working as intended. This could be caused by a recent update that was installed or system files that got corrupted. For
us to resolve your concern, kindly follow the suggested steps below to open an administrator command prompt so that you can run the SFC command:

• Open the regular CMD prompt using the run box (Windows key + R).
• Once you have the CMD prompt open, right-click on the CMD prompt icon on the task bar to open a pop-up menu.
• From the list of options in the pop-up menu look for CMD prompt or
  Windows Command Processor, right-click on the option available that you see.
• Another pop-up menu will show up with the option labeled "Run as administrator". (see the image below for reference)
  
  
  
  

Once you complete the steps above, you will now have a command prompt with administrative rights. As a recommendation, we suggest that you use the option "Pin to taskbar" on the
command prompt with administrative rights so that you can reopen it with ease.

We look forward to your response once you complete the steps.

 

class not registered

Hi Sheila,

The error Class Not Registered may affect many applications. It can be due to changed changes on the Default apps. We'd like to ask the following to help us out on this:

• Can you elaborate the troubleshooting steps that you've done so far?
• Are you able to tell us when did this happened and how long is this ongoing?
• Were there any newly installed applications or updates applied on the device?
• Do you have another user account we can use on your device?
