Start Button/IE Explorer/Microsoft Store not working after Windows 10 Update - 10-12-2016

Following a recent Windows 10 update, the Start Button stopped functioning. IE Explorer will not open.... I get an error message that reads: IE Explorer - Class Not Registered.

The Microsoft store icon does not work either.

I am beginning to get other minor irritating error messages from other applications :

Fax Utility : Error - There is a problem with the parameters for the database library.

The Windows 10 Build is listed as: 14393

Any suggestions from Microsoft?

 

Windows 10 Start Menu File Explorer button error "Windows cannot access the specified device ..."

Hi All,

I have a strange error with windows start menu today! Please check the attached two images:

Notes (before reproducing steps):

• My laptop is up without restart for 11 days till now, I am a software engineer.
• I have ended the explorer processes and relaunched it from the task manager.
• File Explorer button in the start menu opens "This PC".
• I can open the Explorer normally by
  • Menu Button + E
  • File Explorer pinned to the taskbar
• 
  I can't open the File Explorer by Start Menu > File Explorer Button
  
• 
  I don't want to restart, I have a lot of work on other desktops, restart solves this problem. Obviously, it is a bug.
  

Steps to reproduce the error:

• open the start menu
• click on file explorer button
  • an error message appears with "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item".

Step 1:





Step 2 & result:





Steps were taken trying to resolve the issue:

• I tried to restart the explorer process from task manager, but with no success.
• I tried to replace the shortcut the file explorer button points at, but still with no hope.
• I checked the permissions of the "explorer.exe" process in "Windows" folder, and I have the correct permissions. I even tried to double click the file "explorer.exe" and it normally opened the explorer without a problem!

I guess it is a problem with the File Explorer button itself in the start menu (A GUI problem), maybe a corrupted registry key!
