I had an issue with all .exe opening in Notepad
found this 'fix':
HKEY_CLASSES_ROOT\.exe
In right-side pane, change value of Default key to exefile
5. Now go to:
HKEY_CLASSES_ROOT\exefile\shell\open\command
In right-side pane, change value of Default key to:
"%1" %*
But it has now messed up everything, so I cannot even open regedit or any application, manage to get some apps working but manually telling it which app to use, but looking for a fix for this please using Windows 8.1
When I look at any .exe it next to the file type it shows "%1" %*
