Windows 10: Can you install Windows 10 on a formatted PC that used the upgrade from Windows 7

So I'm helping the folks out and need to format their PC. The PC in question has already been upgraded to Windows 10 from 7 a couple of years ago. If I format the computer, install Windows 7 from USB boot, can I still make use of the upgrade to Win 10?

Or, could I use my personal Windows 10 disc/USB boot and use their Windows 7 product key?


Thank-you in advance.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 formatting ?

We upgraded windows 7 to 10. Many crashes and errors after that. So a format and clean install of windows 10. Activated automatically. Zero issues and no more crashes etc etc.
So I'm inclined to say to just go for it. And if a problem, then use your windows 7 key.

 

Installing Windows 10 using Windows 7 key

Hi guys,
Okay, so I wanted to know, I currently have a pc at home with a paid Windows 7 installed. I am getting a new computer either Friday or Monday with an SSD. Seeing as I want Windows 10 now and not 7 and I want it on my SSD how to I get to do this. I already downloaded a Windows 10 file in order to make one of my flash drives eligible for a windows 10 installation.

Will it be possible for me to just install windows 10 on the new SSD with this flash drive using my Windows 7 key, whilst my original windows 7 is still installed on the old Hard drive. And if it is how to I go about deleting my old OS from the HDD, seeing as I also want to use that HDD in my new pc, without formatting all the games I have on it currently?

Thank you in advance
