I had a user complain that his .exe files had changed association to another application and as a result most of programs were not working.
To fix this I had to edit the registry to do this press “Win_key + X” to open the menu and select “Windows Powershell(Admin)” or “Command Prompt(Admin)” if this does not work you need to do one more step and that is to copy c:\windows\system32\cmd.exe to c:\windows\system32\cmd.com and then run c:\windows\system32\cmd.com
Once in the registry navigate to “Computer\HKEY_CLASSES_ROOT\.exe” and change the (default) key data to exefile
Now go to “Computer\HKEY_CLASSES_ROOT\exefile\shell\open\command” and change the (Default) key data to “%1” %*
Once you have made these changes a simple reboot will have the computer functioning again like normal
