Then kindly let me know your company name so I know never to engage your "services".
You just don't get it, do you? YOU may think I'm being dumb but I'm trained, experienced and knowledgeable enough to make up my own mind. So now you're being offensive as well as simply arrogant. You're not the only IT professional around here you know, much less the only one in the world. My own personal and professional experiences lead me to different conclusions than you, that's all. Get off your high horse. There's a line between "no-nonsense" and arrogant and you came across on the wrong side of it.
Where's the cost? I have Win 7 install media and according to the guide that Rob_B helpfully posted I looks like I can use that to roll back. Sure there is my time but this is a favour I'm doing for a friend and I'm prepared to do that. If there was a financial cost in that she'd have to buy the Win7 media and/or licence then we wouldn't be bothering.
LOL, hammering, you're so funny. Your ego is hilarious.
OK so now you've said something relevant to my original question - so are you saying if she buys, say, a Samsung laptop she'll need a Samsung OEM Win7 disc and/or key?
I'm not even discussing this with you any more, you're not prepared to listen to my reasons. I've repeated them two or three times in my previous posts but you just get more aggressive and offensive with each response.
And if you came into my work in a professional capacity and called me stupid you'd be shown the door, immediately.
I'm done here, I'm not wasting any more of my time arguing with you. I'm sure you must have some clients to insult too.
