Windows 10: Explorer.exe stuck in "Class not registered" loop, no metro apps opening, no sound, MMC not...

When I started my Windows 10 computer, after failing to update stuck at 7% 1 of 3, I unplugged, and it tried to undo and restarteD, a few things are happening:


-100% Disk usage.

-Unable to open explorer.exe: it starts for 2 seconds, crashes and restarts immediately.

-No sound whatsoever on the computer.

-Unable to open MMC Class not registered.

-Unable to open any modern application Settings, Explorer apparently the issue is "Class not registered"


I have tried a few several things, to no avail:

-Ran an SFC scannow scan

-Opened in safe mode

-Renamed HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\BannerStore

-regsvr32 ExplorerFrame.dll gives DllRegisterServer not found


The PC is still usable since I have Chrome, but I cannot access the Explorer, Settings app, notification center, or any metro apps

I haven't tried a repair install yet. Any ideas!

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.
