Use previous windows 10(upgraded from Windows 7) Product key(license) for new PC

Hi,

I upgraded my Windows 7(Pro) to windows 10(Pro) in my old PC(laptop) ,Now I have to use new PC(Desktop) since old PC's motherboard is not working.Can I use my previous windows 7(pro) product key to activate freshly install windows 10(Pro) on
new PC?If there any easy steps to follow please mention.

If we can use single Windows 7->10 license in multiple machines(Not sharing license key,PC one at time),How many PCs can use same license key at a time?

Assume :- Current laptop( which has Windows 10 upgraded) is broken,then I will buy another Desktop and,If I can activate windows 10 with previous product key ,and if it;s replaced by another PC or change its Motherboard or processor .How many times current
product key can be extended for separate machines?

Can I transfer my current product key or license to another PC? or Can we uninstall the product key from the current device and use it for another device?

Please help and reply if anyone know the mechanism! asap This is an urgent matter.

Thank you.

 

Product key association disable on old pc

Hey,


I sold my old pc to a friend. He installed some missing parts (HDD, GPU and RAM). Then we installed Windows 10 Home 64-bit version from USB stick. I was surprised to see that windows was automatically activated after that. I did some digging and found out that it is using my product key, which i use now in my own new pc. My friend does not have his own product key, the idea was that he just uses the unactivated windows with limited features.


I uninstalled my Windows 10 product key via command prompt in friends computer (as i understand this is only local solution, if he reinstall windows or clicks the active button, it reactivates automatically with my product key) and now it says windows is not activated, but my product key is still shown with Produkey app in his pc. So far windows is still activated my own pc.


My questions:

1. Is this all i need to do?
2. How do i get rid of product key showing still with product key showing apps on my friend's computer?
3. Is there a way to get rid of association of my product key on that old pc that i sold to friend?

EDIT: I originally installed windows 10 via upgrade option from Windows 7, if that matters.
