DAvehc,
I did read the list you posted. And I did see that my Dell was there. But I didn't realise that the page wasn't about downloads or anything else. My lack of the lingo again. Well, now we know that my pc will take Windows 10 I can forget about buying dodgy stuff from Ebay and get the genuine article.
So I'll finish this thread off now with my thanks to all who posted. You seem an affable and helpful crew. I hope you'll be around once I've installed Windows 10 because I know I'll need some help then alright. To put you in the picture, I'm in my eighties and not the sharpest knife in the box. I'll never be a computer expert.
Good luck and blessings to you all.
Nosebleed.
