Fix minor grammar mistakes.

This is a very useful and functional program for a competitive price - I'm very satisfied.
Just one suggestion is simply go over the program to fix minor grammar issues. Sometimes, the "issue sentences" technically are correct, but can be vague in meaning. For example, under Device Power Management: "Use this option to power off the device after its stopping Windows..." - it took me several moments to figure out its meaning.
Otherwise, as said, this is a great program. Thank you, development team!
