exe files and regedit

I can't access any of my exe files or regedit. Every time I double click on a program, Windows 10 tells me to find an app to open it. When regedit came up the first time, I looked up the steps to getting my exe files to be recognized by Windows 10 and
that didn't work. Now, I can't get regedit to work! i am so frustrated. Could somebody help me and tell me what is going on here please?

 

Unable to open regedit, cmd or any .exe files

Hi, I am encountering a problem that the default app of .exe files has been changed.

While I did some research that many of the solutions suggest that I can reset it via cmd or regedit. However, my oc doesn't let me open any of those.

Everytime I choose to open regedit or cmd. Both of them has the "open with" box popped up, which is the same as other applications.

What is happening to my pc? Can anyone help?

Thanks a lot.
