I've upgraded to windows 10 from 8.1. It seemed to work fine for a while, but there are many things that I can't access.

 

When I click settings, I get this error message:  explorer.exe class not registered.

 

I can't get to windows updates or system restore and many other things. I've searched online and found a few things to try, but nothing is working.

 

Any ideas?  thanks

It looks like you are several Windows 10 builds behind the current version. Specifically, it appears you have the version from December 17, 2015. Please run Windows Update and install the available updates so your build number is 10.0.11102 available on January 13, 2016. Previous versions have been known to have this issue, so I would like to run a bad update out as the cause of the error.

 

After all available Windows updates are installed, please restart your computer and try to go to google.com using the web browser on your computer.

What happens when you try Windows Update? Do you get an error of any kind, or does it perhaps hang on "Checking for updates..."?

I would recommend trying the WinToolkit, it has a module specifically for fixing many Windows Update issues. I've had it bail me.out of several odd cases.

Last resort could be manually downloading updates as the MSI installers. We can probably help you locate the needed updates on Microsoft's website (little hard for me to do on mobile right now).

I can't find windows update at all.  When I click settings I get explorer.exe class not registered.   When I click pc settings, nothing happens.  It's not in control panel at all.

 

I'll find wintoolkit and run that

 

thanks

Please try this.

 

  • Boot the computer into Safe Mode
  • Attempt to start cmd.exe (Run as Administrator through search bar, ALT+F2, Start Menu, Task Manager, etc.)
  • Run the command regsvr32 ExplorerFrame.dll
  • Reboot
  • See if the problem is still present

If that does not work, please boot the computer into Safe Mode, open cmd.exe (Run as Administrator) and run the command sfc /scannow.

As soon as I got into safe mode I got a message saying: sihost.exe system warning  unknown hard error. It wouldn't let me do anything else unless I pressed ok. Then it just went to a black screen. I tried twice
