Thanks to kemical's suggestion in my last thread I used the media creation tool. Took a deep breath and clicked "upgrade now". Off it went installing Win 10. It didn't take all that long. I went off and did some other things while it was updating. I'm guessing it took well under 30 minutes to the final desktop. Never asked for a key either. When it was done I thought nothing had updated. My desktop was the same as before with the same wall paper and shortcuts. It wasn't until I went to the start button that I saw all the new goodies. Everything seems to be working just fine so far. I could do without the white background in Edge but I'm sure there is a way to change it. Not a big deal. This upgrade is easily the least painful of any I've done since the early MS-DOS days......
