Win10 Upgraded from Win7 - new build need to re-install O/S

HiWhats the best procedure to reinstall Win10, if you took the free upgrade from Win7? i'm now on the Win10 Creators edition, but changing everything over this weekend, new mobo, gpu ........ and so on. What's the procedure seeing that this is completely new hardware... Where's the best place to get the ISO ? also what happens when it asks me to enter in a serial key? Just skip and login using my microsoft account that knows i have an lic associated to my Microsoft sign-on ?Thanks

The free digital license that you got for W10 on the old motherboard is not transferable so it will not be possible to use your Microsoft account and hope that it will automatically activate.

The official route is to buy a new W10 OS, however, there are reports that the free upgrade from W7 and W8 is still working so you might want to give that a try.

Even though i had a full retail license of Win7

OK, I've just gone over the rules again and you will be able to activate by using your Microsoft Account (MSA) but you will need to use the activation troubleshooter and you will need to be on the Anniversary update or Creators Update. Don't think of the license as attached to the MSA, but instead think of the MSA as having the authority to transfer the license.

See this tutorial: Link Microsoft Account to Windows 10 Digital License

Before changing any components I would create a new Windows 10 ISO using the media Creation tool that you can use to install on the new build. See the first part of the following tutorial: Clean Install Windows 10

Thanks, i was a little disheartened to read the first reply.. Like what i have all this fancy new hardware and now i'm going to have to buy a new license at $200 Noooooooooooooooooooooo :) I'll have a read up later on, but just wanted to say thanks for the links.

You are welcome, I was a bit hasty with my first reply and had given you the answer that was correct before the anniversary update. The new changes have made things a bit easier.
