Windows 10: Free upgrade from Win 7 to Win10?

My partner has Windows 7 installed on her PC. It also has a nasty virus. I want to erase her hard drive and upgrade to Windows 10. I've read articles that indicate the upgrade is still free, if done through Windows updates. I can't find anything confirming that it's still free if I format the disk. Does anybody else know? We have the product key, is there anything else we need? I can't really afford to buy it.

is hardware OK (Win 7) for upgrade to windows 10

I think in one of the other PC with win 7 or win 8.1 I run media creators tools and in some step prompt/found graphics card not supported... for win 10. I didn't found alone reading specs of win 10, but the tool says me... after changed graphics card the tool said all OK and continued OK with upgrade... That I ask to reach this step in this current PC - win 7 - must be all OK for the upgrade? Or must continue to upgrade to show this?
and got to point

• UPGRADE this PC now
• Create media(DVD, USB stick, ISO)

is hardware OK (Win 7) for an upgrade to windows 10 for this PC???

Upgrading Win 7 Pro to Win 10

Hi Once Again

I just finished performing the steps you suggested I do in your last email to upgrade from Win 7 Pro to Win 10. I eliminated all of the temporary files and then performed a check disk on my hard drive; no errors or bad sectors were found. After doing those
steps, Win10 failed to install again so then I went back and performed all of your suggest procedures from the past several emails all at once....disconnecting all of my external devices, doing the system file check, and then deleting all of the temporary
files following by the check disk routine. Once again the Win10 download failed to install.

This is what happened when I tried the upgrade: I began the download from the Microsoft flag download icon in my bottom toolbar rather than using the Media Creation tool program applet that had tried several times before to upgrade windows.. The download
preceded normally and then the computer went into the installation process. The preparing for upgrade splash panel came up and then the desktop showed configuring update for Windows 10 appeared. The upgrade got to 87% complete once again and then my computer
went into the reboot mode. The computer rebooted back into Win 7. The Windows update panel appeared with a panel that said "upgrade to Win10....start installing the newest versions of windows". I did not get a Win 10 failed to install as I did when using the
Media Creation tool.

As I said, the reboot took me right back into my normal Windows 7 screen which worked normally.

That's all the information I have this time around.
