You need to upgrade which ever OS before RTM as RTM goes over qualifying OS. But I believe Win 7Sp1=Win 10 Home, you want Pro Put Genuine key in now-RTM over that
That will upgrade to Win 10 Home, you want pro I think, but as it stands now you need to download Win 10 Home not Pro
no i want try make install win 7 pro sp1 and put original key so if take the upgrade have win 10 geniune can i???
AFAIK Windows 7 Pro SP1 will be updated to Windows 10 Pro! May have to read the blog from Gabe Aul again?!!
Er.....!! Sorry, I was late and read even the post and directly answered, should have read further instead!! Sorry again!
Ultimate You don't use key in upgrade, it reads it from OS that's under, does it say that Win 7 Ultimate is Genuine?
