Hey,
Microsoft has implied but not confirmed that you need to upgrade the in-place Windows 7.
Microsoft keeps confusing people with Windows 10. They said you could apply a clean install after upgrading first but AFAIK have not absolutely confirmed you MUST upgrade first. Sigh.
The only text I've seen says 'upgrade first, then clean install'
We shall see.
And I agree. Wait until after the actual release for further info.
The only information I can find is this:
" i would also know this. what happens after i have to reinstall my Windows 10 after 29.07.2016..."
reply is:
"Once you upgrade W10 w/ the free upgrade offer you will able to clean reinstall Windows 10 on same device any time... "
So the question was what happens AFTER I have already upgraded but nowhere could I find information that confirmed or denied you could do a fully clean (blank drive) installation of the RTM version then simply apply your W7 or W8.1 serial to activate.
For that matter what about the Preview version? Can someone validate that with a W7/W8.1 code if unused or already activated for the same system? (You will be able to buy a W10 code without reinstalling at least).
Every time someone asks Microsoft to confirm something about W10 they give an incomplete answer. It's really frustrating.
Upgrading to Windows 10 then doing a clean install isn't hard since I already have W8.1 however if I had an unused installation disc for W7/W8.1 I surely wouldn't want to install that, upgrade, wipe all that and do a clean install.
