';control his PC '; ... wow . sounds like a hacker's job .it kinda possible , but it would say it's tooo messy and only complicate things more than it is . whatever the problem is , either guide him through the internet , phone , any alternative . or just come straight to his house . it is not recommended , or that it's easier , than just doing it the old fashion way.
