Windows 10: how do i activate windows 10 on a new computer without using the key currently connected to...

I am going to build a new desktop computer soon, i allready have a laptop with windows 10 activated with a retail key, which is connected to my account. i am wondering if i can disconnect my microsoft account from the windows key on my laptop, and then connect a new key to my account and use it on my new computer?

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 Hardware change

No. That only applies to an OEM key. IF you had a retail key that you upgraded, you are more than welcome to transfer this key to another device, just as you would have been able to before the upgrade. The default for retail keys is three activations before you need to call in and get help with activation. Previously, it was required that you install your retail OS first and then upgrade, but the most recent build of Win10 removes that requirement and allows direct installation of Windows10 using your retail Win7/8/8.1 key.

 

Need help with transferring Windows 10 to new PC

*Nevermind I figured it out. I just bought a license key for $29.00. Thx though.
So my friend asked me to build him a new computer for work. The last one I built him was during the windows 7-10 upgrade grace period. I used to load windows 7, use windows loader to put in a product key, activate it, then upgrade to windows 10. Now that the grace period is over, and I'm working with new hardware, I was wondering if it is possible to install windows 10 from an already functioning computer that operated on a sata SSD to a new computer with an m.2 nvme SSD, using just the product key from the current windows 10 off of his computer. I use a program that grabs the product key called ProduKey.
Should I do a fresh install of windows 10 using his key after deactivating it from his current PC , instead of cloning drives correct? It would be nice not to have to pay microsoft $200 for windows 10 if he already has it and plans on not using his old pc anymore.
