Windows 10: Class not registered

So I've been having this error since my computer updated yesterday and everytime I boot it up and login explorer is not running so I manually start it up. Once I do that my sound stops working and if I try to open videos images or even the main windows settings it tells me class not registered. I've tried almost every single thing in all of the videos except for the last one because I can't access settings to set everything to default. Please help

:)

 

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?

Hi Eddie,

class not registered

Neither Edge or the start menu will load on my computer. It just comes up with X class not registered.

Any suggestions?
