Can I clone a drive and free upgrade one to Windows 10 for future use?

[Marco_man]

I have a Lenovo Thinkpad and I have hard drive cloning software. I want to take advantage of the free upgrade from Windows 7 to Windows 10 which expires this week, but I don't plan on using Windows 10 for a long while, if ever. My idea would be to clone my existing windows 7 hard drive to a separate hard drive. Then on one of the two hard drives I would do the upgrade. I would then remove that upgraded hard drive and install the other hard drive into my computer so I am still running Windows 7. I would simply set aside the upgraded hard drive until some future, long term, time when I felt like switching to Windows 10. Is that reasonably possible or would there be complications with licensing? Thanks

yes you can do that.
No licensing issues if you activate the windows and use it in the same machine later.

As long as it's used on the Lenovo Thinkpad , it would be fine , the license is tied to it.​
