Unable to open Notepad or MS Paint

I have a desktop PC with Windows 10. I use both Notepad and MS Paint frequently and they both recently stopped opening. Clicking the taskbar shortcuts to open them doesn't cause them to open; the mouse switches to the "loading" throbber, but reverts back after about a second without opening any windows. The same thing occurs when I locate the *.exe files in the system32 folder. There is no error message or change in state to screenshot.

The following descriptions say "Notepad," but in each case I have tried the steps for both MS Paint and Notepad, and I'm looking for help with both. Based on suggestions from around the internet I have tried:

1. running notepad as an administrator (both from the taskbar shortcut and by locating notepad.exe in the file explorer).
   
2. resetting the cache for the Windows store (using "WSReset.exe") and then running notepad.
   
3. uninstalling and then reinstalling notepad via Settings>Apps and features>Optional features.
   
4. restarting computer
   
5. updating computer and then restarting
   
6. uninstalling notepad, restarting, reinstalling notepad.
   

Windows specifications from Settings>System>About are:

Notepad consuming cpu 40%

Your screenshot of Task Manager and the notepad.exe properties shows the same size and creation date as in @dalchina's earlier screenshot. So it looks like it is the real notepad that's running.

But - it isn't running the way it should. In your Task Manager there should be a > to the left of notepad, and clicking on it should open up a list of the Notepad instances that are running, along with the name of the document that's open (or 'Untitled - Notepad' if none).

Yours doesn't show that (compare it with dalchina's screenshot). Notepad is running - yes, but not the way it's supposed to. It appears to be in the list of background processes, not in the list of Apps where it should be. Could something be trying to run it as a service? Perhaps some malware set this up, but failed to replace the genuine notepad.exe with its counterfeit one?

As a first step I'd look at the Startup tab in Task Manager for clues.
