do you see a need to open each file in notepad,
using editor instance to manipulate it
and then using notepad instance to save and close it?
It could be done with plain file read/write as well.
Test the script extensively before using it in production
Assumptions done by the following script is
Folder as workspace is visible
The word looking for is exactly Hello, not hello or HELLO …
Only the root directory is scanned for files having .txt extension, no recursion aka subdirectories are searched.

UPDATE: open the python script console to see which file gets manipulated
