Thanks a lot for the code! Just one comment - the current version will fail if the PS1 file contains the character ' in its name and you try to run it as administrator.

I have fixed this by changing

'-ExecutionPolicy Bypass -File \\\"%1\\\"'

into

\"\"\"-ExecutionPolicy Bypass -File \\\"\\\"%1\\\"\\\"\"\"\"

that only uses the double quote " character (which cannot appear in filenames in Windows).

Thanks, @tomasz1986!

I didn't even think about this problem. Now it's fixed 🤝
