That sucks if I have to install twice to get a clean install. Even worse, when I get around to building a new system, I'll have to install Win7, upgrade to Win10 then re-install Win10. SIW discontinued the free version and the last free version doesn't work on Win8/10, so unless there is another way to get the license key, I have to keep backups of install media for each system.
1) Unless you have an ancient system, the upgrade only takes a few minutes. The same goes for the (unnecessary) "clean" install. This is not Windows 98. Do some research. It takes only a few minutes to install Win 10 from scratch.
2) It has been known for MONTHS now and posted all over relevant threads/sites that you absolutely do NOT have to go through the ordeal of a Win 7/Win 8 reinstall. You just install Win 10 with a generic key and if the activation gives you crap about a changed hardware ID you call MS and have them reset your stuff (or follow their instructions to actually go legit and BUY a new Win 10 license... whatever they will tell you... at the very latest after July 29, 2016
they will probably tell you to fuck off and buy Win 10).
You need to let go off the thought of having a unique key with Win 10. You don't. You just need any old generic key for the install. The only thing that counts is the activation which creates a unique hardware ID on Microsoft's activation backend and binds it to your Win 10 install.
Also, once you convert your Win 7/8.x license to a Win 10 license, you might be able to reinstall Win 7/8.x with your original key BUT you won't be able to activate it so you will have to get in touch with MS in any case. Might as well skip the reinstall and install 10 with a generic key, then call them and explain why you require a reset.
