Windows 10: Explorer.exe Class not found

So hey guys, I'm in a bit of a sticky situation here. So I booted up my computer on Monday, loaded fine and everything seemed to work until i tried opening the file explorer, when boom error message.





Being an Com Sci major and having some experience with viruses and windows misbehaving, I went straight into trying to trying to fix my issue, but it wasn't as simple as i thought it would be.

Firstly i did a complete scan with Malwarebytes and it found 'Legit.BatBitRst' which is an adware trojan. Malwarebyte got rid of it and i thought my problem was solved. No it wasn't.

So i went online looking up this issue. Found that i might just need to reregister the explorerframe.dll. That didn't work either:





So in doing some more reading i saw were it might be some windows feature settings related to IE and Edge so i tried opening control panel:





I even tried windows update to see if that would help but when i click update and security in settings, it just quits.

I've tried sfc/scannow which said that some files are corrupted but it couldn't fix them, did the dism/online thing after which completed successfully but didn't solve the issue after running sfc/scannow again.

CBS.log.zip

Remove the .zip extension to access the file. It was just renamed with notepad++

Only things that I have not tried, is doing a clean boot, or a safe boot; and currently my other antivirus software, Eset Smart Security, is doing a deep administrative scan of the App Data, Program Data, and Windows folders, but i dont have my hopes up as the last scan it did came back clean.

So i'm at my wits end, any help with this issue would be greatly appreciated.

Windows 10 Enterprise x64
Intel i5-3210M 2.6GHz(3.0GHz)
Nvidia GT635M 1GB
8GB RAM (7.9 usable)
700GB HDD

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.
