I wanted to add the option to create a new Mardown file to the context menu in Windows 10. Its a really simple process.
Step 1. Open regedit using Run.
Step 2. Go to HKEY_CLASSES_ROOT .
Step 3. Find the extension type, in my case .md.
Step 4. Create a new key named: ShellNew.
Step 5. In this newly created key, create a string named: NullFile and assign it a value of 1.
That's it!
Now you will be seeing your new file type extension in the new context menu of Windows.
