Windows 10: Can I transfer a Windows 10 Home product key to another PC if I'm planning on upgrading...

I have 2 computers, a laptop that I recently got which is a Windows 10 Home and an older desktop which is a Windows 7 Home.

I'm planning on upgrading my laptop to Windows 10 Pro.

Can I use the product key from the Windows 10 Home version to upgrade my desktop?

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.

 

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.

 

Building a new rig to transfer Windows 10 but not sure if it's OEM or Retail

If you upgraded from a retail box copy Windows 7, it has retail transfer rights.

Use the following to see if you can find the original Windows 7 key. If you can't find the original Windows 7 key, you won't be able to transfer it.
