Windows 10: upgrading PC completely, want to use existing Windows 10 license on new computer and no...

If I were to install Windows 10 or 11 directly from USB flash drive onto brand new motherboard CPU SSD combo, can I use my existing Windows 10 key?

Windows 10 upgrade license

The interesting question is that: the upgrade takes place before 29 of July. If I upgrade the PC (change the MB), and I transfer the Win 8.1 license to this new PC (cause 8.1 is retail FPP), will I be able to upgrade to Windows 10 for free? Or a upgrade license must be bought?

 

Windows 10 upgrade license

Hello guys,

I have 1 license of WIndows 8.1 FPP/retail license. I want to upgrade to WIndows 10, but I one thing is unclear to me.
If I upgrade, will WIndows 10 license be retail or it will "turn" into some sort of OEM license?

I ask this because I upgrade my PC, you know, more memory, replace HDD, and I intend to upgrade the MB and CPU to Kaby Lake platform sometime in the future, (and of course sell the replaced hardware)
This thing is not clearly mentioned anywhere.

Thank you.

 

Windows 10 License question - New PC and old computer still exists.

Hi Microsoft Community!

I'm in the process of assembling a new PC and am going to give the old PC to my younger brother. I want to transfer my existing license to the new computer and if possible "de-license" the old one. These are the particulars:

• My Windows 10 license was purchased on the Microsoft website and originally activated with a product key.
• I still have this product key.
• I have since formatted the PC and after re-installing Windows 10 the activation is now with a digital license.
• I prefer using local accounts on my PC and thus haven't created a Microsoft account enabled user.

My question is how to best go about transferring the license? Can I just format the old PC and activate my license on the new PC with the product key? If I do that will I get a problem when my brother installs Windows on the old computer again, since it
now has a digital license?

Any help would be greatly appreciated!
