I received the sign up for free win10 upgrade in my taskbar.
I did this with an email address. But I have more win7 computers than I have email address'
Will I be able to use the same iso / serial / key to upgrade all of my win7 computers?
Or will the serial key be generated by my email address?
I got the same deal and did the install today...then I reverted back to W7 after I used W10 for about an hour. When you get the notification about the download, you follow the onscreen instructions and it will be an auto download and install with just a few options along the way that will allow you SOME leeway in what is installed and how you can customize.
After using for about an hour, I just wasn't satisfied with the user interface as it is presented now. I perhaps could have grown used to the new look, but I would rather wait until the inevitable SP1 comes along.
What REALLY disappointed me was the fact the games (I know, I know) were no longer part of the installed programs, they are now an ONLINE APP! In order to play them, you must have a Microsoft account in order to keep a running tab on your statistics. That sucks the big weenie!
