I am guessing that the product key and license key is different? I keep hearing that you first must do and update and then you can do a fresh install.
I don't think there is a different key you have to use since it is a free upgrade. Downloading installer to flash drive ATM and plan to nuke mine tonight.
Yes, its completely seperate, actually its a pain in the ass. In order to get a "free" copy of 10, you must upgrade (install over and from within) a legal copy of 7 or 8.1 first, once you do that, then your activation key is saved on M$'s servers, and you can do a wipe and clean install from that point forward on that device (supposedly infinite times as they say "for the life of the device"). It is keyed to a hardware profile, so once you upgrade the motherboard or cpu (or whatever they are keying off of), that key is no longer any good, and you cannot get your free copy back.
There is a loophole though if you want a free copy of 10 without paying for it (and without using a legal 7 or 8.1 to upgrade from), you can sign up to be a "windows insider". The issue here is you are trading all of your telemetry and product usage stats for a free OS, and you are also a guinea pig for all the new builds and testing (although you can slow installs down by going to the slow ring). The question here is though, is it worth it? Just read though the agreement you accept, they record EVERYTHING, silly things like how long your mouse cursor is in what area of the screen. I had no problems with that when I was using it every once in a while to test things, but I'm not sure if I want them recording everything on a machine I use for my daily things. Seems a bit worse than Google if you ask me.
Curious to hear your take on the update process, look/feel of the new UI, and end results as they pertain to this and other steam games. I hope you post an update...
Let us know how the fresh install goes. I think a lot of people are waiting to hear how everything goes down before the commit to the migration so it would be a service to the community.
I've been running the tech preview on a removable drive since December. Its not all that bad, I still like Win7 best. I haven't done an upgrade of an old win7 or 8.1 system though, only a fresh install of win10 and then updates to the builds (which are upgrade installs). Its come quite a way since last December. All of my software seems to work fine, I haven't run into any compatibility issues with software. Nvidia drivers work perfectly, even got SLI to work. The only issue I have is my older soundblaster card every once in a while craps out and stops working. Creative has an eta of August to have it fixed. My fix is to just delete it from the device manager, and let it reinstall, then it works for a while again. shrug.
All in all, its not all that bad of an OS, and I've used hundreds of different OS's over the years. Solaris is by far the worst one I've ever had to use.
For those of you that are on the fence about it and want to test it out, download one of those iso's, and install it inside a VM like
https://www.vmware.com/products/player. And when it asks you for a product key a few times, you can skip it and let it install and use it before the activation locks you out of things. Its a VM so its not going to be able to game and such, but you can at least play with the start menu and default software to see if its something you want to use.
I guess there is a rollback feature to roll 10 back to the original OS, but its only good for 30 days. Not sure why they put an expiration date on it though.
