Need to ReInstall Windows 10 home 64-bit, Please help methods?

I have Windows 10 Home 64bit and need to reinstall it, not clean install, and I no disc or product or license for it. I upgraded to Windows 10 from Windows 7 back when doing so was 100% free, so I do have a legit version Windows 7 siting here.

What method, or methods, are safe and easy to do a repair install of windows 10 home 64bit under my situation?

Repair Install Windows 10 with an In-place Upgrade

and here is where to get the Windows 10 ISO file:

Upgrading is still enabled if you have a valid Win 7 key, so that's always one option (supposedly, it's for people who use assistive technology - but MS are a bit woolly about the fine detail, it seems). Anyway - a sequence that still works is:

• get hold of a copy of the Win 10 install (e.g. the ISO file linked to in another post in this thread)
• do a basic install of WIn 7
• activate your Win 7 key
• run the Win 10 install over the top, and select the option to upgrade your OS when the choice comes up

I had to go round that loop myself only a few days ago. I found that a few of the Win 10 device drivers needed updating once it came up, but apart from that it was pretty painless, and seems to have worked fine.

Why install Windows 10 a second time? That has never been necessary.

Sorry, yes, OP said a reinstall. The sequence I mentioned works to do a full, clean install of Win 10 using a Win 7 key. There may well be be other, easier options even for that; I'm no expert.

I was speaking about your sequence to do a full, clean install of Windows 10 using a Windows 7 product key to activate. There is an easier option. Leave out the last step of reinstalling Windows 10 a second time it isn't necessary.

You can actually skip the activation screen and it should auto activate if the machine had a running version of Win 10
