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?
  

 

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.
